Change Sema::CheckAddressOfOperation() to respect C99-only addressof rules.
...
Remove diagnostics from Sema::CheckIndirectionOperand(). C89/C99 allow dereferencing an incomplete type. clang appears to be emulating some incorrect gcc behavior (see below).
void
foo (void)
{
struct b;
struct b* x = 0;
struct b* y = &*x; // gcc produces an error ("dereferencing pointer to incomplete type")
}
With this patch, the above is now allowed.
