This is in preparation for future changes in AMDGPU that will make more
substantial use of bundles pre-RA. For now, simply test this with
degenerate (single-instruction) bundles.

TargetInstrInfo now directly holds a reference to TargetRegisterInfo
and does not need TRI passed in anywhere.

If the instruction with tied operands is a BUNDLE instruction and we
handle it by replacing an operand, then we need to update the
corresponding internal operands as well. Otherwise, the resulting MIR is
invalid.

The test case is degenerate in the sense that the bundle only contains a
single instruction, but it is sufficient to exercise this issue.

This is a low level utility to parse the MCInstrInfo and should
not depend on the state of the function.

Add per-property has<Prop>/set<Prop>/reset<Prop> functions to
MachineFunctionProperties.

This `AA` parameter is not used and for most uses they just pass
a nullptr.

The use of `AA` was removed since 8d0383e.
