Subject: [PATCH] Move getNumFrameInfos and getDwarfFrameInfos out of line and
 remove the MCDwarf.h include.

This removes 50 transitive dependencies for a modification of
MCDwarf.h in a build of llc for a pair of out of line functions
and reduces the build overhead of 'touch MCDwarf.h" by 15% without
impacting test time of check-llvm.
