[PATCH] tree-ssa-mathopts: Use proper poly_int64 comparison with param_avoid_fma_max_bits [PR 98766]

[Kyrylo Tkachov via Gcc-patches]

Hi all,

We ICE here because we end up comparing a poly_int64 with a scalar using <= 
rather than known_le.
This patch fixes that in the way richi suggests in the PR.

Bootstrapped and tested on aarch64-none-linux-gnu.
Ok for trunk?

Thanks,
Kyrill
