Justin Becker 638329278c Inlined PCMPXSTRX ...

Improves performance for SSE4.2 String operations by ~10x by emitting inline ASM instead of jumping to a C++ helper.

Performance numbers from a simple microbenchmark vs the existing C++ implementation:
|               | Equal Any | Ranges | Equal Each | Equal Ordered |
|---------------|-----------|--------|------------|---------------|
| **pcmpestri** | 13.40×    | 9.71×  | 19.38×     | 14.07×        |
| **pcmpestrm** | 13.12×    | 9.54×  | 18.73×     | 13.80×        |
| **pcmpistri** | 11.75×    | 9.19×  | 17.63×     | 12.80×        |
| **pcmpistrm** | 11.39×    | 8.83×  | 16.31×     | 12.26×        |
