C++ PATCH for c++/82115, ICE with variable initialized to own address


In this testcase, we consider the initializer of b to decide if it's
value-dependent, but the initializer mentions b, so we were recursing
infinitely.  But if we're interested in the address, we don't care
about the value; we already handle that appropriately in the constexpr
code, this patch updates value_dependent_expression_p accordingly.

Tested x86_64-pc-linux-gnu, applying to trunk.
