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.
