Reid Kleckner 257cb4e099 [InstCombine] Fix !prof metadata preservation for invokes 
Summary:
Bug noticed by inspection.

Extend the test to handle invokes as well as calls, and rewrite it to
not depend on the inliner and other passes.

Also simplify the call site replacement code with CallSite, similar to
what I did to dead arg elimination and arg promotion (rL300235 and
rL300229).

Dehao Chen fed890ea3a Fix the InstCombine to reserve the VP metadata and sets correct call count. 
Summary: Currently the VP metadata was dropped when InstCombine converts a call to direct call. This patch converts the VP metadata to branch_weights so that its hotness is recorded.
