	dependences for TSan for aarch64-*-linux* targets.

62c0f0a637 Update libsanitizer obstack interceptors
New obstack uses sensible types, size_t instead of int for length
params.  Since libsanitizer does not use prototypes from obstack.h to
call the real functions, it's necessary to update the libsanitizer
function declarations emitted by the INTERCEPTOR macro.

	* sanitizer_common/sanitizer_common_interceptors.inc: Update size
	params for _obstack_begin_1, _obstack_begin, _obstack_newchunk
	interceptors.
	* configure.ac: Substitute OBSTACK_DEFS.
	* asan/Makefile.am: Add OBSTACK_DEFS to DEFS.

f35db108b9 Import the asan runtime library into GCC tree
This patch imports the runtime library in the GCC tree, ensures that
-lasan is passed to the linker when -faddress-sanitizer is used and
sets up the build system accordingly.

ChangeLog:

	* configure.ac: Add libsanitizer to target_libraries.
	* Makefile.def: Ditto.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
	* libsanitizer: New directory for asan runtime.  Contains an empty
	tsan directory.

gcc/ChangeLog:

	* gcc.c (LINK_COMMAND_SPEC): Add -laddress-sanitizer to link
	command if -faddress-sanitizer is on.

libsanitizer:

	Initial checkin: migrate asan runtime from llvm.
