Finish up handling all permutations of "complex int" (in Sema::UsualArithmeticConversions()).
...
A FIXME remains to verify the conversion rules are consistent with GCC.
Thanks to Eli for the new/improved test case...

- Change Type::isComplexType() to exlude GCC's complex integer extension. In general, we will keep the lowest level Type predicates "pure" (i.e. true to the C99 spec).
...
- Modify Sema::UsualArithmeticConversions() to work with the new definition of Type::isComplexType().
This is a nice cleanup and also fixes a bug submitted by Eli (which I've added to the test suite).

Record if a compound literal expression is @ file scope. This allows us to implement C99 6.5.2.5p6. This could have been done without modifying the AST (by checking the decl type and passing the info down to isContextExpr), however we concluded this is more desirable.

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.

Merge all the 'assignment' diagnostic code into one routine, decloning
...
it from several places. This merges the diagnostics, making them more
uniform and fewer in number. This also simplifies and cleans up the code.
Some highlights:
1. This removes a bunch of very-similar diagnostics.
2. This renames AssignmentCheckResult -> AssignConvertType
3. This merges PointerFromInt + IntFromPointer which were always treated the same.
4. This updates a bunch of test cases that have minor changes to the produced diagnostics.
