c++: add fixed testcase [PR99804]

We accept the non-dependent call f(e) here ever since the
NON_DEPENDENT_EXPR removal patch r14-4793-gdad311874ac3b3.
I haven't looked closely into why but I suspect wrapping 'e'
in a NON_DEPENDENT_EXPR was causing the argument conversion
to misbehave.

	PR c++/99804
