As part of this effort, remove MipsFCmp nodes and use tablegen
patterns rather than custom lowering through C++.

Unexpectedly, this improves codesize for microMIPS as previous floating
point setcc expansions would materialize 0 and 1 into GPRs before using
the relevant mov[tf].[sd] instruction. Now $zero is used directly.
