  Revert "[fastalloc] Support allocating specific register class in fastalloc"

This reverts commit 719658d078c4093d1ee716fb65ae94673df7b22b.
Breaks a few things, see comments on https://reviews.llvm.org/D128437
There's disagreement about the best fix.
So let's keep HEAD green while discussions are happening.
