Re-land "[ThinLTO] Add call edges' relative block frequency to per-module summary."

It was reverted after buildbot regressions.

Original commit message:

This allows relative block frequency of call edges to be passed
to the thinlink stage where it will be used to compute synthetic
entry counts of functions.
