45789b63db libm: Add hardware sqrt, ceil, floor and trunc for x86 & x86_64 
Add hardware implementations for sqrt, ceil, floor and trunc for
x86 and x86_64. These routines, and in particular sqrt are much
faster than the BSD C language versions of these functions.

Fixed whitespace errors.

Revised x86 versions with respect to alignment.
Rebased for Android 5.0
