Change subject: x86: Replace getDoubleBits with floatToBits64.
......................................................................
x86: Replace getDoubleBits with floatToBits64.
The getDoubleBits function was used exactly once to find the bit
representation of a double floating point value, which is the same thing
the common floatToBits64 function does. Eliminate x86's one off version,
and use the common one instead.
