gollvm: initial support for Auto-FDO

Support the -fsample-profile-use= and -fdebug-info-for-profiling
command line options, along with driver changes to enable Auto-FDO.

[Note: Go function/package names cause issues "create_llvm_prof";
without a separate fix to that tool the optimization gains from
AutoFDO will be degraded.]
