Start to disallow llvm.frameaddress and llvm.returnaddress in ABI checker.
They do not seem to be widely used by user code.
* The boehm garbage collector library does reference
__builtin_return_address under an ifdef, but it
does not appear to be compiled in.
* Mesa-7.6 uses __builtin_frame_address
for u_debug_stack.c, but that also does not appear to be
part of the built libraries.
They expose stack/code addresses (at least the lower
32-bits of the address).
As part of https://codereview.chromium.org/14619022/,
we stopped considering the scons and gcc torture tests that
use these intrinsics as meeting the stable ABI.
