Demo patch for LLD that stops parsing .eh_frame during GC stage

is: https://reviews.llvm.org/D40484. With it LLD GC code is slightly simpler.

I tested it both together with lib/mc patch for emiting multiple .eh_frames

(https://reviews.llvm.org/D40352) and along, it looks it has no any visible effect on

perfomance by itself.
