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.
