c++: non-static member, decltype, {} [PR100205]

This test was fixed by my second patch for PR93314, which distinguishes
between constant-expression and potentially-constant-evaluated contexts in a
way that my first patch did not.

	PR c++/100205
	PR c++/99314

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/decltype-nonstatic1.C: New test.
