[llvm-dev] Enabling EarlyCSE w/ MemorySSA by default

[Geoff Berry via llvm-dev]

Hi All,

I'd like to switch the function simplification run of EarlyCSE to use 
MemorySSA by default.  This change has been in tree for a while and I've 
done benchmark and self-hosting testing on both aarch64 and x86, but I 
wanted to give other folks with different tests/targets a chance to try 
this out before I flip the switch. I've added an option 
'-enable-earlycse-memssa' (or '-enable-npm-gvn-hoist' if you're using 
the new pass manager) that you can be used to test this change out.

Thanks,
