pulley: Fill out most remaining simd float ops (bytecodealliance#9884)

alexcrichton · web-flow · commit fc3c868b13bc · 2025-01-06T18:34:12.000Z
* pulley: Fill out most remaining simd float ops

Get most simd/float-related tests passing. Mostly reusing preexisting
scalar ops for the simd implementation.

* Fix fma test on MinGW

prtest:full

* More MinGW fixes
