LibWasm: Fix some floating-point conversion issues

Browse Source 
NaN bit patterns are now (hopefully) preserved. `static_cast` does not
preserve the bit pattern of a given NaN, so ideally we'd use some other
sort of cast and avoid `static_cast` altogether, but that's a large
change for this commit. For now, this fixes the issues found in spec
tests.
