	Check if instruction A comes before B, where A and B both belong to the MachineFunction passed to initialize().

Detailed Description

Record instruction ordering so we can query their relative positions within a function.

Meta instructions are given the same ordinal as the preceding non-meta instruction. Class state is invalid if MF is modified after calling initialize.
