When preparing a corpus of SPIR-V shaders for fuzzing, spirv-as is
invoked repeatedly. It could be that a bug in spirv-as leads to
conversion failing for some of the shaders. This should not prevent the
overall corpus from being generated, as long as the number of overall
failures is reasonably small. This change adds some tolerance for such
failures.

This currently only changes the way that Expressions are traversed. We

During HexFloat parsing, if exponent was too large, we would overflow
the signed integer being used to store its value. We now use an uint32_t
to avoid UB, then convert to int32_t when it's safe to do so.
Also error out if the input exponent is > INT_MAX - 127, which ensures
we will not wrap around and produce an invalid result when adding the
exponent bias of 127.
