X87: [wasm] Fix I32ReinterpretF32 and I64ReinterpretF64 on ia32.

  port ea9254317149c7904a7bf6bc821af35958e4da7f (r42545)

  original commit message:
  On ia32 return statements in C++ automatically convert signalling NaNs
  to quiet NaNs, even when bit_cast is used. This CL removes all uses of
  bit_cast<float> and bit_cast<double> in the wasm compiler and wasm
  interpreter.
