libsanitizer merge from upstream r250806, compiler part.
gcc/
* asan.c (asan_emit_stack_protection): Don't pass local stack to
asan_stack_malloc_[n] anymore. Check if asan_stack_malloc_[n] returned
NULL and use local stack than.
(asan_finish_file): Insert __asan_version_mismatch_check_v[n] call
in addition to __asan_init.
* sanitizer.def (BUILT_IN_ASAN_INIT): Rename to __asan_init.
(BUILT_IN_ASAN_VERSION_MISMATCH_CHECK): Add new builtin call.
* asan.h (asan_intercepted_p): Handle new string builtins.
* ubsan.c (ubsan_use_new_style_p): New function.
(ubsan_instrument_float_cast): If location is unknown, assign
input_location to loc. Propagate loc to ubsan_create_data if
ubsan_use_new_style_p returned true.
config/
* bootstrap-asan.mk: Replace ASAN_OPTIONS=detect_leaks with
LSAN_OPTIONS=detect_leaks.
gcc/testsuite/
* c-c++-common/ubsan/float-cast-overflow-10.c: Adjust test.
* c-c++-common/ubsan/float-cast-overflow-8.c: Likewise.
* c-c++-common/ubsan/float-cast-overflow-9.c: Likewise.
