Thanks Peter for pointing me to something that should have never been
committed to the llvm code base.

e89ada98a6 Add some dead stores to pacify my least favorite GCC warning: may be
uninitialized. The warning is terrible, has incorrect source locations, and has
a huge false positive rate such as *all* of these.

If anyone has a better solution, please let me know. Alternatively, I'll
happily add -Wno-uninitialized to the -Werror build mode. Maybe I can even do
it *only* when building with GCC instead of Clang.

remove that exception (InstructionSimplify handles this so there should
be no loss).

e60d79faf7 Add a rather pointless InstructionSimplify transform, inspired by recent constant
folding improvements: if P points to a type of size zero, turn "gep P, N" into "P".
More generally, if a gep index type has size zero, instcombine could replace the
index with zero, but that is not done here.

c1da204c43 apply Dan's fix for PR8268 which allows constant folding to handle indexes over

into an empty function.
