[WebGPU] fast math leads to invalid code gen
https://bugs.webkit.org/show_bug.cgi?id=285938
rdar://142906182
Reviewed by Tadeu Zagallo.
It is too easy to generate MSL with -ffmast-math which LLVM optimizes
more agressively than expected, due to LLVM being able
to prove a certain expression is Inf or NaN and can therefore
be discarded under fast math optimization rules.
Instead, use relaxed math which honors NaNs and Infs but still
largely preserves performance.
