[GCC] Update with latest retpoline fixes from Intel.

2018-01-29T22:19:21+00:00

Intel has updated their retpoline patches since we created our
original patch.  This CL updates our retpoline changes to match
the latest from Intel.

Bug: None
Test: Tested extensively in ChromeOS.  Built x86 platform & kernel
images in Android.

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

2018-01-08T18:25:12+00:00

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.
