[PATCH] D151782: Improve WebAssembly vector bitmask, mask reduction, and extending

[Caleb Zulawski via Phabricator via llvm-commits]

Since this has been reverted, I'm just updating the complete patch here.

All I changed was allowing unexpected vector lengths to lower as usual.  Codegen for unusual vector lengths is still very bad--there should be an additional step somewhere that breaks up bitcasts to legal vector lengths (the X86 codegen does this before MOVMSK, but I can't figure out how).
