[X86] Changing the check for valid inputs in combineScalarToVector Changing the logic of scalar mask folding to check for valid input types rather than against invalid ones, making it more robust and fixing PR37879. Differential Revision: https://reviews.llvm.org/D48366 llvm-svn: 335323

[X86] Remove the suffix on vcvt[u]si2ss/sd register variants in assembly printing. We require d/q suffixes on the memory form of these instructions to disambiguate the memory size. We don't require it on the register forms, but need to support parsing both with and without it. Previously we always printed the d/q suffix on the register forms, but it's redundant and inconsistent with gcc and objdump. After this patch we should support the d/q for parsing, but not print it when its unneeded. llvm-svn: 360085

[X86] Remove the changes to combineScalarToVector made in r335037. They appear to be untested other than the test case for p37879.ll and I believe we should be using SimplifyDemandedElts here to handle these cases. llvm-svn: 335436
