JitArm64: Use one instruction for making NaNs quiet
Instead of materializing the quiet bit in a register and ORing the NaN
with it, we can perform an arithmetic operation on the NaN. This is a
cycle or two slower on some CPUs in cases where generating the quiet bit
pipelined well, but this is farcode that rarely runs, so instruction
fetch latency is the bigger concern. And for non-SIMD cases, we also
save a register.
