syscall: fix creds_test to reliably close os.File

Uncovered by Uros Bizjak.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.

On my system:

[asan] Instrument built-in memory access function calls

This patch instruments many memory access patterns through builtins.

Basically, for a call like:

     __builtin_memset (from, 0, n_bytes);

the patch would only instrument the accesses at the beginning and at
the end of the memory region [from, from + n_bytes].  This is the
strategy used by the llvm implementation of asan.

This instrumentation is done for all the memory access builtin
functions that expose a well specified memory region -- one that
explicitly states the number of bytes accessed in the region.

A special treatment is used for __builtin_strlen.  The patch
instruments the access to the first byte of its argument, as well as
the access to the byte (of the argument) at the offset returned by
strlen.

For the __sync_* and __atomic* calls the patch instruments the access
to the bytes pointed to by the argument.

While doing this, I have added a new parameter to build_check_stmt to
decide whether to insert the instrumentation code before or after the
statement iterator.  This allows us to do away with the
gsi_{next,prev} dance we were doing in the callers of this function.

Tested by running cc1 -fasan on variations of simple programs like:

    int
    foo ()
    {
      char foo[10] = {0};

      foo[0] = 't';
      foo[1] = 'e';
      foo[2] = 's';
      foo[3] = 't';
      int l = __builtin_strlen (foo);
      int n = sizeof (foo);
      __builtin_memset (&foo[4], 0, n - 4);
      __sync_fetch_and_add (&foo[11], 1);

      return l;
    }

and by starring at the gimple output which for this function is:

    ;; Function foo (foo, funcdef_no=0, decl_uid=1714, cgraph_uid=0)

[asan] Make build_check_stmt accept an SSA_NAME for its base

This patch makes build_check_stmt accept its memory access parameter
to be an SSA name.  This is useful for a subsequent patch that will
re-use.

Tested by running cc1 -fasan on the program below with and without the
patch and inspecting the gimple output to see that there is no change.

void
foo ()
{
  char foo[1] = {0};

  foo[0] = 1;
}

* asan.c (build_check_stmt): Accept the memory access to be
represented by an SSA_NAME.

plain move cases into two, one for memory accesses and one for
register accesses.  Generalize the memory case, freeing it from
the old register-based endian checks.  Move the INT_MODE calculation
above the code that needs it.  Use simplify_gen_subreg to handle
multiword OP0s.  If the field still spans several words, pass it
directly to extract_split_bit_field.  Assume after that point
that both targets and register sources fit within a word.
Replace x-prefixed variables with non-prefixed forms.
