Josh Poimboeuf 63a94b8323 gcc-plugin: create a ppc64le GCC plugin which inserts nops after local calls
This is in response to an upstream discussion for the following patch:

  https://lkml.kernel.org/r/1508217523-18885-1-git-send-email-kamalesh@linux.vnet.ibm.com

This should hopefully make it a lot easier for the ppc64le kernel module
code to support klp relocations.

The gcc-common.h and gcc-generate-rtl-pass.h header files are copied
from the upstream Linux source tree.
