  Log Message:
  -----------
  [ThinLTO] Compute the basic block count across modules.

Summary:
Count the per-module number of basic blocks when the module summary is computed
and sum them up during Thin LTO indexing.

This is used to estimate the working set size under the partial sample PGO.

This is split off of D79831.
