Maciej W. Rozycki 198f70589e MIPS: math-emu: Add IEEE Std 754-2008 ABS.fmt and NEG.fmt emulation 
Implement IEEE Std 754-2008 non-arithmetic ABS.fmt and NEG.fmt emulation
wired to the state of the FCSR.ABS2008 bit.  In the non-arithmetic mode
the sign bit is altered according to the operation requested regardless
of the datum encoded in the input operand, no other bits are changed,
the resulting bit pattern is written to the output operand and no
exception is ever signalled.
