a method named ImpCastExprToType in Sema.

Use this method to insert implicit casts for case statements from their 
operand type to the condition type of the switch.  This fixes a crash on
test/CodeGen/statements.c, reported by Eli Friedman.

Cleaned up GRConstants::AddBinding to not directly reference the
predecessor node.  Now we just manipulate the current state, and a driver
function creates nodes as needed.

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...

llvm-svn: 46022

- 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).

Rework commit r45976, which was incorrect.

- Add Type::isComplexIntegerType(), Type::getAsComplexIntegerType().
- Don't inlude complex types with Type::isIntegerType(), which is too general.
- Use the new predicates in Sema::UsualArithmeticConversions() to recognize/convert the types.

serializing the subexpression (Init), as this results in a more efficient
encoding in the bitstream.

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.
