x64: port fcmp to ISLE (#3967)

Browse Source 
* x64: port scalar `fcmp` to ISLE

Implement the CLIF lowering for the `fcmp` to ISLE. This adds a new
type-matcher, `ty_scalar_float`, for detecting uses of `F32` and `F64`.

* isle: rename `vec128` to `ty_vec12`

This refactoring changes the name of the `vec128` matcher function to
follow the `ty_*` convention of the other type matchers. It also makes
the helper an inline function call.

* x64: port vector `fcmp` to ISLE
