Use "-all1" option will test the fxx_mulAdd, which is not a unary function

[RolfyYu]

In "testfloat.c":
line 1683~1686, fxx_mulAdd is not labeled as "FUNC_ARG_BINARY",
so the code logic will put fxx_mulAdd into all1 list.

You're absolutely right about the bug, though not about the correct fix, since the multiply-add functions aren't binary either.

This was made to work properly in testsoftfloat a long time ago, but I evidently forgot to upgrade testfloat at the same time. As it happens, I'm already working on the next release (3e). I'll include the correction for this issue in that realease.

[jhauser-ucberkeley]

This mistake is believed to be fixed in Release 3e.

confirm that -all1 option is fixed.
