  Log Message:
  -----------
  [NFCI][InstCombine] Move store merging from `visitStoreInst()` into `visitUnconditionalBranchInst()`

Summary:
As @nikic is pointing out in https://bugs.llvm.org/show_bug.cgi?id=46680#c5,
InstCombine should not have forward instruction scans,
so let's move this transform into the proper place.

This is pretty much NFCI.
