AMDGPU/SI: Set the kill flag on temp VGPRs used to restore SGPRs from scratch
Summary:
When we restore an SGPR value from scratch, we first load it into a
temporary VGPR and then use v_readlane_b32 to copy the value from the
VGPR back into an SGPR.
We weren't setting the kill flag on the VGPR in the v_readlane_b32
instruction, so the register scavenger wasn't able to re-use this
temp value later.
I wasn't able to create a lit test for this.

AMDGPU/SI: SGPR accounting in getSIProgramInfo must ignore exec_lo/hi
Summary:
A shader stored the live mask (initial exec mask) in an SGPR which was then
spilled during register allocation. The allocator quite reasonably
optimized turned the spill into
v_writelane_b32 %vgpr, exec_lo, N
v_writelane_b32 %vgpr, exec_hi, N+1
at the beginning of the shader, confusing the SGPR accounting.
No test case, because si-sgpr-spill.ll together with an upcoming patch for
WQM handling exhibits the problem.

AMDGPU/SI: Use v_readfirstlane to legalize SMRD with VGPR base pointer
Summary:
Instead of trying to replace SMRD instructions with a VGPR base pointer
with an equivalent MUBUF instruction, we now copy the base pointer to
SGPRs using v_readfirstlane.
This is safe to do, because any load selected as an SMRD instruction
has been proven to have a uniform base pointer, so each thread in the
wave will have the same pointer value in VGPRs.
This will fix some errors on VI from trying to replace SMRD instructions
with addr64-enabled MUBUF instructions that don't exist.

Make LIBOMP_USE_ITT_NOTIFY a setting that can be enabled or disabled
On Blue Gene/Q, having LIBOMP_USE_ITT_NOTIFY support compiled into a
statically-linked binary causes a failure at runtime because dlopen fails.
This patch changes LIBOMP_USE_ITT_NOTIFY to a cacheable configuration setting
that can be disabled.

Allow unit testing on Windows
These changes allow testing on Windows using clang.exe.
There are two main changes:
1. Only link to -lm when it actually exists on the system
2. Create basic versions of pthread_create() and pthread_join() for windows.
They are not POSIX compliant by any stretch but will allow any existing
and future tests to use pthread_create() and pthread_join() for testing
interactions of libomp with os threads.

When MemoryDependenceAnalysis hits a CFG with many transparent blocks,
the algorithm easily degrades into quadratic memory and time complexity.
The easiest example is a long chain of BBs that don't otherwise use a
location. The caching will add an entry for every intermediate block and
limiting the number of results doesn't help as no results are produced
until a definition is found.
Introduce a limit similar to the existing instructions-per-block limit.
This limit counts the total number of blocks checked. If the limit is
reached, entries are considered unknown. The initial value is 1000,
which avoids regressions for normal sized functions while still
limiting edge cases to reasnable memory consumption and execution time.

[X86] Remove transformVSELECTtoBlendVECTOR_SHUFFLE
The new X86 shuffle lowering can do just fine without transforming vselects
into vector_shuffles. It looks like the only thing this code does right now
is cause trouble - in particular, it can lead to combine/legalization infinite
loops.
Note that it's not completely NFC, since some of the shuffle masks get inverted,
which may cause slight differences further down the line. We may want to find
a way to invert those masks, but that's orthogonal to this commit.
This fixes the hang in PR27689.

Use absolute module path when possible if sent in svr4 packets
Summary:
If the remote uses svr4 packets to communicate library info,
the LoadUnload tests will fail, as lldb only used the basename
for modules, causing problems when two modules have the same basename.
Using absolute path as sent by the remote will ensure that lldb
locates the module from the correct directory when there are overlapping
basenames. When debugging a remote process, LoadModuleAtAddress will still
fall back to using basename and module_search_paths, so we don't
need to worry about using absolute paths in this case.

Fixed the failing test TestCommandScriptImmediateOutput on MacOSX. Turns out that there are few things to watch out for when writing pexpect tests:
1 - If you plan on looking for the "(lldb) " prompt as a regular expression, look for "\(lldb\) " so you don't just find "lldb".
2 - Make sure to not use colors (specify --no-use-colors as an option to lldb when launching it) as our editline will print:
"(lldb) <color junk>(lldb) "
where "<color junk>" is a work around that is used to allow us to colorize our prompts. The bad thing is this will make pexepct code like this not execute as you would expect:
prompt = "\(lldb\) "
self.child.sendline("breakpoint set ...", prompt)
self.child.sendline("breakpoint clear ...", prompt)
The problem is the first "sendline" will create two lldb prompts and will match both the first and second prompts and you output will get off. So be sure to disable colors if you need to.
Fixed a case where "TestCommandScriptImmediateOutput.py" would fail if you have spaces in your directory names. I modified custom_command.py to use shlex to parse arguments and I quoted the file path we sent down to the custom_command.write_file function.

Maintain register numbering across xml include features
Summary:
If the remote uses include features when communicating
xml register info back to lldb, the existing code would reset the
lldb register index at the beginning of each include node.
This would lead to multiple registers having the same lldb register index.
Since the lldb register numbers should be contiguous and unique,
maintain them accross the parsing of all of the xml feature nodes.

Properly unload modules from target image list when using svr4 packets
Summary:
When we receive an svr4 packet from the remote, we check for new modules
and add them to the list of images in the target. However, we did not
do the same for modules which have been removed.
This was causing TestLoadUnload to fail when using ds2, which uses
svr4 packets to communicate all library info on Linux. This patch fixes
the failing test.

Store absolute path for lldb executable in dotest.py
Summary:
lldb-server tests are currently being skipped on the
check-lldb target. This is because we get the path of
lldb-server by modifying the path to the lldb executable.
However, by this point, we've changed directories, and a
relative path to the build/bin directory will no longer point
to the location of lldb-server.
Storing an absolute path solves this issue.

Allow gdbremote process to read modules from memory
Summary:
The logic to read modules from memory was added to LoadModuleAtAddress
in the dynamic loader, but not in process gdb remote. This means that when
the remote uses svr4 packets to give library info, libraries only present
on the remote will not be loaded.
This patch therefore involves some code duplication from LoadModuleAtAddress
in the dynamic loader, but removing this would require some amount of code
