f56d44dbb2 [lanai] Use peephole optimizer to generate more conditional ALU operations. 
Summary:
* Similiar to the ARM backend yse the peephole optimizer to generate more conditional ALU operations;
* Add predicated type with default always true to RR instructions in LanaiInstrInfo.td;
* Move LanaiSetflagAluCombiner into optimizeCompare;
* The ASM parser can currently only handle explicitly specified CC, so specify ".t" (true) where needed in the ASM test;
* Remove unused MachineOperand flags;

d35aaca112 [lanai] isBrImm should accept any non-constant immediate. 
isBrImm should accept any non-constant immediate. Previously it was only accepting LanaiMCExpr ones which was wrong.
