[X86] Allow PSHUFD/PSHUFLW/PSHUFW intrinsics in constexpr. (#161210)
The i16/i32 shuffle intrinsics (`pshufw`, `pshuflw`, `pshufhw`,
`pshufd`) currently cannot be used in constant expressions. This patch
adds support in both bytecode interpreter (InterpBuiltin.cpp) and
constant evaluator
(ExprConstant.cpp) for pshuf intrinsics, enabling their use in constant
expressions.
## Intrinsics covered
- `_mm_shuffle_pi16` (MMX `pshufw`)
- `_mm_shufflelo_epi16` / `_mm_shufflehi_epi16`
- `_mm_shuffle_epi32`
- Their AVX2/AVX512 vector-width variants
- Masked and maskz forms (handled indirectly via
`__builtin_ia32_select*`)
Fixes #156611
