  SOUND: Remove a case of implementation-specific code in WMACodec

The code made two assumptions:
1) floats are IEEE floats, because it manually manipulated the sign
bit of a float reinterpret_cast'd to a uint32
2) left-shifting a negative int works and fills with zeroes

This commit gets rid of these assumptions by replacing a substraction
with a branch and a shift-and-xor with a float multiplication.
