I found this while trying to figure out how to get VRP to optimize:
a_1 != 0 into a_1 if the range of a_1 is [0,1] (well with a NOP_EXPR).
If I do it inside simplify_cond_using_ranges, I miss all the MODIFY_EXPRs.

For x86, there is no difference in the code gen for f and f1/f2, but for PPC32,
there is:
for f1/f2:
addic %r0,%r31,-1
subfe %r3,%r0,%r31
For f:
srawi %r3,%r31,31
subf %r3,%r31,%r3
