7451d3e09d SelectionDAG shouldn't have a FunctionLoweringInfo member. RegsForValue
shouldn't have a TargetLoweringInfo member. And FunctionLoweringInfo::set
doesn't needs its EnableFastISel argument.

05ce489871 Merge the SystemZ subreg_even32 SubRegIndex into subreg_32bit. The SubRegIndices
were overspecified when inheriting sub-subregisters, for instance:

R0Q:subreg_even32 = R0Q:subreg_32bit = R0Q:subreg_even:subreg_32bit.

This meant that composeSubRegIndices(subreg_even, subreg_32bit) was ambiguous.

2da5337024 Add a TargetRegisterInfo::composeSubRegIndices hook with a default
