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.
