QFMA/QFMS instructions (#2328)

Renames the SIMDBitselect class to SIMDTernary and adds the new
{f32x4,f64x2}.qfm{a,s} ternary instructions. Because the SIMDBitselect
class is no more, this is a backwards-incompatible change to the C
interface. The new instructions are not yet used in the fuzzer because
they are not yet implemented in V8.

The corresponding LLVM commit is https://reviews.llvm.org/rL370556.
