Detailed Description

Defines a builder that does CSE of MachineInstructions using GISelCSEInfo.

Eg usage.

GISelCSEInfo *Info =
    &getAnalysis<GISelCSEAnalysisWrapperPass>().getCSEInfo();
CSEMIRBuilder CB(Builder.getState());
CB.setCSEInfo(Info);
auto A = CB.buildConstant(s32, 42);
auto B = CB.buildConstant(s32, 42);
assert(A == B);
unsigned CReg = MRI.createGenericVirtualRegister(s32);
auto C = CB.buildConstant(CReg, 42);
assert(C->getOpcode() == TargetOpcode::COPY);

Explicitly passing in a register would materialize a copy if possible. CSEMIRBuilder also does trivial constant folding for binary ops.
