Add more SIMD math.h intrinsics
LLVM supports many functions from math.h in its IR. Many of these have single-instruction variants on various platforms. So, let's add them so std::arch can use them. Yes, exact comparison is intentional: rounding must always return a valid integer-equal value, except for inf/NAN.
