oneAPI, intel icx/icpx: Fix compile warnings "explicit comparison with infinity in fast floating point mode"

[stolsvik]

Feature Description

Would be nice to not have lots of compile warnings.

These are present for multiple files, most notably in ggml.c:

Motivation

It is a bit demotivating to see quite a bit of compile warnings when compiling a program.

Evidently these didn't matter, yi-34b-chat.Q6_K.gguf runs just fine. However, on my Xeon 6150, there was exactly 0 speedup by using oneAPI, so I am not sure it actually runs the code that possibly could be hit by these warnings?
