Simon Dardis 730fdb73a1 [mips] Correct c.cond.fmt instruction definition. 
Permit explicit $fcc<X> operand in c.cond.fmt instruction.

Add c.cond.fmt to the MIPS to microMIPS instruction mapping table.

Check that $fcc1 - $fcc7 are unusable for MIPS-I to MIPS-III for
c.cond.fmt, bc1t, bc1f.

Simon Dardis 9c34854833 [mips] synci microMIPS instruction definition. 
Add synci to the microMIPS instruction definitions, mark the MIPS sync & synci
as not being part of microMIPS. This does not cover the sync instruction alias,
as that will be handled with a different patch. Add sync to the valid tests for
microMIPS.

Simon Dardis ba92b034bf Revert "[mips] Fix c.<cc>.<fmt> instruction definition." 
This reverts commit r281022. Mips buildbot broke, due to unhandled register
class FCC.

Simon Dardis 8efa979029 [mips] Fix c.<cc>.<fmt> instruction definition. 
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.
