[PATCH] D109481: [WebAssembly] Custom optimization for truncate

[Thomas Lively via Phabricator via llvm-commits]

tlively added a comment.

@jingbao I was working on landing this, but the `CodeGen/WebAssembly/fpclamptosat_vec.ll` test had to be updated. Unfortunately Phabricator won't let me attach the changes to this revision, but it looks like this change introduces some new unnecessary masking that was not there before in a couple of the test functions. (It also makes a bunch of good changes!). Would you be able to take a look at that? I'd also be ok with landing this as-is since the improvements looks more significant and more common than the regression.
