c++: Mark __builtin_convertvector operand as read [PR93557]
In C++ we weren't calling mark_exp_read on the __builtin_convertvector first
argument. I guess it could misbehave even with lambda implicit captures.
Fixed by calling decay_conversion on the argument, we use the argument as
rvalue so we want the standard lvalue to rvalue conversions, but as the
argument must be a vector type, e.g. integral promotions aren't really
needed.

* semantics.c (cp_build_vec_convert): Call decay_conversion on arg
prior to passing it to c_build_vec_convert.
* c-c++-common/Wunused-var-17.c: New test.
