This patch defines a new intrinsic function
__builtin_speculation_safe_value. A generic default implementation is
defined which will attempt to use the backend pattern
"speculation_safe_barrier". If this pattern is not defined, or if it
is not available, then the compiler will emit a warning, but
compilation will continue.
Note that the test spec-barrier-1.c will currently fail on all
targets. This is deliberate, the failure will go away when
appropriate action is taken for each target backend.
