So it's the following passes (if you ignore that with -fopenacc we already
fold b_c_p during early opts):
NEXT_PASS (pass_vrp, true /* warn_array_bounds_p */);
NEXT_PASS (pass_dce);

Note in all cases of the testcases coming with the patch the sources are
eventually casted from float to double.

The transformation is from:
_663 = T1$1_55 + _293;
_651 = (float) _663;
where T1$1_55 and _293 are doubles. To:
_758 = (float) T1$1_55;
_759 = (float) _293;
_760 = _758 + _759;
_651 = (float)
