Stephen Canon 7e326063c5 Concrete SIMD operations, part 1 (#36172) ...

Adds concrete overloads of the following SIMD operations:
- Comparisons: .==, .!=, .<, .<=, .>, .>=
- Logical operations on masks: .!, .&, .^, .|
- Integer arithmetic: &+, &-, &, &+=, &-=, &=
This makes some simple benchmarks 10-100x faster, which is basically a no-brainer, while staying away from the most heavily used operators, so hopefully doesn't impact compilation performance too badly.
