Andrew Kaster 9a66a9ac4a LibWasm: Split SaturatingTruncate conversion function by float/non-float ...

It's possible to construct a floating point value that when converted to
double is not larger than i64::max(), but when remaining a float is
larger. This patch avoids that edge case with some even less exciting if
constexpr branches to fix a float-cast-overflow UBSAN error on macOS
with llvm 15.0.6.
