[Bug c++/41431] New: &main should be allowed within unevaluated operands.

[schaub-johannes at web dot de]

The following code snippet is wrongly rejected

int main() { sizeof(&main); }

---
main.cpp: In function 'int main()':
main.cpp:1: warning: ISO C++ forbids taking address of function '::main'
---

But the Standard allows that within a sizeof, because according to 3.2/2 it
does not constitute a "use" of main.
