[Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - add PSLL/PSRA/PSRL var intrinsics to be used in constexpr #169176
Description
Add constexpr handling and test coverage for the variable splat vector shifts - its unlikely we can reuse the existing interp__builtin_elementwise_int_binop handling used by other x86 vector shifts intrinsics.
These are going to be a little messy because the lower 64-bits of the unsigned count operand is used for the shift amount for all types (SRA clamps to BW-1 but SLL/SRL return zero for out of bounds values), which requires concatenation of the lower vector elements for vXi16/Xi32 types - see X86InstCombineIntrinsic.cpp simplifyX86varShift for examples.
