[PATCH] D36636: [GISel][NFC]: Add some constructors for easy creation of MIRBuilders

[Aditya Nandakumar via Phabricator via llvm-commits]

aditya_nandakumar created this revision.

Add some constructors for easier use of MIRBuilders in backend code/passes.
Currently to use the MIRBuilder, we need
MIRBuilder B;
B.setMF(MF);
B.setInstr(SomeMI);
It would be easier to just do
MIRBuilder B(MF, SomeMI);
