* ARM: Implemented floating-point negation and abs() for softfloat using integer instructions. Fixes webtbs/tw4534.pp, and also yields much faster code than existing implementation.
Background: these operations are defined as flipping or clearing the upper bit of number, respectively, and never result in precision loss or raise floating-point exceptions.
