[GCC] Commit retpoline patch code, for fixing security issues.

This applies the Intel GCC code patches, to allow compiling
with appropriate flags for mitigating the indirect branch variant of
the speculative execution security flaw.

Bug: None
Test: This is already in place in ChromeOS and has been tested on
the ChromeOS kernels.
