[Sanitizers] Add new sanitize-stable-abi flag for libsanitizers.

This patch adds a new flag sanitize-stable-abi to support linking
against the Sanitizers stable ABI added recently in compiler-rt. The
patch also passes extra options for the ASan pass when using this flag
to outline instrumentation code and remove version check.
