Pull compiler hardening updates from Kees Cook:
 "These are various compiler-related hardening feature updates. Notable
  is the addition of an explicit limited rationale for, and deprecation
  schedule of, gcc-plugins.

  gcc-plugins:
   - remove support for GCC 4.9 and older (Ard Biesheuvel)
   - remove duplicate include in gcc-common.h (Ye Guojin)
   - Explicitly document purpose and deprecation schedule (Kees Cook)
   - Remove cyc_complexity (Kees Cook)

  instrumentation:
   - Avoid harmless Clang option under CONFIG_INIT_STACK_ALL_ZERO (Kees Cook)

  Clang LTO:
   - kallsyms: strip LTO suffixes from static functions (Nick Desaulniers)"
