EOF is detected.

418d80e555 The memcpy intrinsic only takes i8* for %src and %dst, so cast them to that 
first. Fixes PR7265.

bdfc4b7cd0 Allow for creation of clang DeclNodes tables. 
The StmtNodes generator has been generalized to allow for the
creation of DeclNodes tables as well, and another emitter was
added for DeclContexts.

ed310b8bca SelectionDAG shouldn't have a FunctionLoweringInfo member. RegsForValue 
shouldn't have a TargetLoweringInfo member. And FunctionLoweringInfo::set
doesn't needs its EnableFastISel argument.

b3539aa611 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.

6a3738d96a 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.
