[X86] When handling addcarry intrinsic, create the flag result with the correct type so we don't crash if we use a memory instruction Summary: Previously we were creating the flag result with MVT::Other which is interpretted as a Chain node. If we used a memory form of the instruction we would end up with a copyToReg that consumed the chain result of the adcx instruction instead of the flag result. Pretty sure we should be using MVT::i32 here, that's what we do other places we create these node types. We should probably consider this for 5.0 as well.

[X86] When handling addcarry intrinsic, create the flag result with the correct type so we don't crash if we use a memory instruction Summary: Previously we were creating the flag result with MVT::Other which is interpretted as a Chain node. If we used a memory form of the instruction we would end up with a copyToReg that consumed the chain result of the adcx instruction instead of the flag result. Pretty sure we should be using MVT::i32 here, that's what we do other places we create these node types. We should probably consider this for 5.0 as well.

[X86] Change the addcarry and subborrow intrinsics to return 2 results and remove the pointer argument. We should represent the store directly in IR instead. This gives the middle end a chance to remove it if it can see a load from the same address. Differential Revision: https://reviews.llvm.org/D51769 llvm-svn: 341677
