PR68264: Use unordered comparisons for tree-call-cdce.c

As reported in PR 68264, tree-call-cdce.c should be using unordered
comparisons for the range checks, in order to avoid raising FE_INVALID
for quiet NaNs.

Tested on x86_64-linux-gnu and aarch64-linux-gnu.  The test failed on
aarch64-linux-gnu before the patch, but it didn't on x86_64-linux-gnu
because it used unordered comparisons for the previous ordered tree codes.
