This patch add the necessary bits to suport libasan on FreeBSD x86_64.
gcc
* config/i386/i386.h: Define a new macro: SUBTARGET_SHADOW_OFFSET.
* config/i386/i386.c (ix86_asan_shadow_offset): Use this macro.
* config/i386/darwin.h: Override the SUBTARGET_SHADOW_OFFSET macro.
* config/i386/freebsd.h: Likewise.
* config/freebsd.h (LIBASAN_EARLY_SPEC): Define.
LIBTSAN_EARLY_SPEC): Likewise. (LIBLSAN_EARLY_SPEC): Likewise.
libsanitizer:
* configure.tgt: Add x86_64- and i?86-*-freebsd* targets.
