and increases spills. Nothing really scary here, and in many ways validates

optimizer.
I've also found one case where stack coloring appears to just fail for no
reason: "NArchive::N7z::GetStringForSizeValue(unsigned int)" in
7zHandler.cpp has exactly the same sequence of instructions after the
change but 3x larger stack. But this appears to be rare and mostly relating
to functions with already small stack sizes. I've filed PR28821 to track
this.
Anyways, while clearly...

RFC: We should stop merging allocas in the inliner
Chris added alloca merging in the inliner a looooong time ago, 2009. The
reason he added it was because at the time we didn't do stack coloring and
without it we had serious stack size problems in LLVM.
Since then, a few rather important things have changed:
- We have reasonably powerful stack coloring support in the backend based
on lifetime markers
- Clang (the primary frontend I'm
