Jakub Jelinek 5d3805fca3 ubsan.c (ubsan_expand_null_ifn): Use _v1 suffixed type mismatch builtins...
* ubsan.c (ubsan_expand_null_ifn): Use _v1 suffixed type mismatch
	builtins, store max (log2 (align), 0) into uchar field instead of
	align into uptr field.
	(ubsan_expand_objsize_ifn): Use _v1 suffixed type mismatch builtins,
	store uchar 0 field instead of uptr 0 field.
	(instrument_nonnull_return): Use _v1 suffixed nonnull return builtin,
	instead of passing one address of struct with 2 locations pass
	two addresses of structs with 1 location each.
	* sanitizer.def (BUILT_IN_UBSAN_HANDLE_TYPE_MISMATCH,
	BUILT_IN_UBSAN_HANDLE_TYPE_MISMATCH_ABORT,
	BUILT_IN_UBSAN_HANDLE_NONNULL_RETURN,
	BUILT_IN_UBSAN_HANDLE_NONNULL_RETURN_ABORT): Removed.
	(BUILT_IN_UBSAN_HANDLE_TYPE_MISMATCH_V1,
	BUILT_IN_UBSAN_HANDLE_TYPE_MISMATCH_V1_ABORT,
	BUILT_IN_UBSAN_HANDLE_NONNULL_RETURN_V1,
	BUILT_IN_UBSAN_HANDLE_NONNULL_RETURN_V1_ABORT): New builtins.

	* c-c++-common/ubsan/float-cast-overflow-1.c: Drop value keyword
	from expected output regexps.

	* g++.dg/ubsan/float-cast-overflow-bf.C: Likewise.
	* gcc.dg/ubsan/float-cast-overflow-bf.c: Likewise.
	* g++.dg/asan/default-options-1.C (__asan_default_options): Add
	used attribute.
	* g++.dg/asan/asan_test.C: Run with ASAN_OPTIONS=handle_segv=2
	in the environment.

	* All source files: Merge from upstream 315899.
        * asan/Makefile.am (nodist_saninclude_HEADERS): Add
	include/sanitizer/tsan_interface.h.
        * asan/libtool-version: Bump the libasan SONAME.
	* lsan/Makefile.am (sanitizer_lsan_files): Add lsan_common_mac.cc.
	(lsan_files): Add lsan_linux.cc, lsan_mac.cc and lsan_malloc_mac.cc.
        * sanitizer_common/Makefile.am (sanitizer_common_files): Add
