math/test: Allow user to set control element of input vector
argf and argd have been designed such that non-special input is
tested, optionally followed by a vector with one special lane. To be
able to test that vector functions have correct behaviour w.r.t. fenv
exceptions, we need to be able to choose a different value for the
last lane, as using 1 leads to false negatives when testing a function
for which 1 is a special value. We add an option, -c, for the user to
provide a different control value.
