John Stiles 48b27317b4 Fix fuzzer-discovered error with range checks. 
The fuzzer managed to create a NaN using a carefully-crafted mix of
intrinsics and constant folding. (`cosh(421)` is a very large double,
which becomes +Inf when cast to float, which is then multiplied by 0;
zero times infinity is NaN.)

Our code which checked to see if a value is in range of an int did not
consider NaNs and their always-false behavior, so it incorrectly
decided that NaN was in range. This CL reverses the check so that a NaN
will not pass, but all other values will behave the same.

Followup CLs should probably also tighten up the folding/optimizer
behavior so that NaNs/Infs are not created at all.
