Taylor Simpson 1a442c0931 Hexagon (target/hexagon) Change subtract from zero to change sign
The F2_sffms instruction [r0 -= sfmpy(r1, r2)] doesn't properly
handle -0.  Previously we would negate the input operand by subtracting
from zero.  Instead, we negate by changing the sign bit.

Test case added to tests/tcg/hexagon/fpstuff.c
