MIR Parser: make the machine instruction parsing interface more consistent. NFC.

Browse Source 
This commit refactors the interface for machine instruction parser. It adopts
the pattern of returning a bool and passing in the result in the first argument
that is used by the other parsing methods for the the method 'parse' and the
function 'parseMachineInstr'.
