Bitwise conversions doesn't preserve the bits in the polyfill for Firefox

1

When doing bitwise conversion of int32x4->float32x4->int32x4 the bits aren't preserved for Firefox, when NaN patterns are present. This code: ``` var i4 = SIMD.int32x4(0x7fc00000,0x7fe00000,0x7ff00000,0x7ff80000); var i4c = SIMD.int32x4.fromFloat32x4Bits(SIMD.float32x4.fromInt32x4Bits(i4)); ``` results...
