stage1: add support for @mulAdd fused-multiply-add for floats and vectors of floats

Not all of the softfloat library is being built....

Vector support is very buggy at the moment, but should work when the bugs are fixed.
(as I had the same code working with another vector function, that hasn't been merged yet).
