* rtl.h (REG_EH_REGION): Update comment to indicate a value of -1
indicates no throw and no nonlocal gotos.
* optabs.c (emit_libcall_block): Emit REG_EH_REGION with a value
of -1 instead of 0 to indicate a nonlocal goto won't happen either.
* flow.c (count_basic_blocks, find_basic_blocks_1): Ignore libcall
blocks, look for REG_EH_REGION note exclusively.
(make_edges): Check for REG_EH_REGION > 0 for specified handlers.
