This commit goes through the `runtests` folder of the `filetests`
test suite and ensure that everything which uses simd or float-related
instructions on x64 is executed with the baseline support for x86_64 in
addition to adding in AVX support. Most of the instructions used have
AVX equivalents so this should help test all of the equivalents in
addition to the codegen filetests in the x64 folder.
Remove the boolean types from cranelift, and the associated instructions breduce, bextend, bconst, and bint. Standardize on using 1/0 for the return value from instructions that produce scalar boolean results, and -1/0 for boolean vector elements.
Fixes#3205

`fmin`/`fmax` are defined as returning -0.0 as smaller than 0.0.
This is not how the IEEE754 views these values and the interpreter was
returning the wrong value in these operations since it was just using the
standard IEEE754 comparisons.
This also tries to preserve NaN information by avoiding passing NaN's
through any operation that could canonicalize it.
