abrown opened PR #1246 from refactor-simd to master:

Before adding the remaining SIMD instructions, I thought it would be good to clean up the current implementation. I have tried to be very careful to avoid any change to behavior when renaming/moving things around. The changes are:

• To reduce compile times (along the lines of #1168), I separated out some instructions and legalizations into their own define methods
• For filetest clarity, I renamed all x86 SIMD filetests with a simd- prefix and removed the %test_ prefix of the individual test functions (I've noticed that Cranelift chops off the ends of those functions so the test_ prefix can hide which test is failing)

Please keep comments wrapped at 100 columns or so (which is the rustfmt column limit, except it doesn't automatically split up comments).

As we discussed offline, this is a run test, so it naturally uses the host as the target.
