Jakob Stoklund Olesen 417fc5e434 Emit TargetRegisterInfo::composeSubRegIndices(). 
Also verify that all subregister indices compose unambiguously.

Jakob Stoklund Olesen e02996ca8f 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.

Jakob Stoklund Olesen 64824ea99f Add a TargetRegisterInfo::composeSubRegIndices hook with a default 
implementation that is correct for most targets. Tablegen will override where
needed.

Add MachineOperand::subst{Virt,Phys}Reg methods that correctly handle existing
subreg indices when sustituting registers.
