Check each case value in turn while parsing it, performing the
conversion to the switch type within the context of the expression
itself. This will become necessary in order to properly handle cleanups
for temporaries created as part of the case label (in an upcoming
patch). For now it's just good hygiene.
This necessitates moving the checking for the switch condition itself to
earlier, so that the destination type is available when checking the
case labels.
As a nice side-effect, we get slightly improved diagnostic quality and
error recovery by separating the case expression checking from the case
statement checking and from tracking whether there are discarded case
labels.

have integral or enumeration type, so that we still check the contents
of the switch body. My previous patch made this worse; now we're back
to where we were previously.

enumeration type out into a separate, reusable routine. The only
functionality change here is that we recover a little more
aggressively from ill-formed switch conditions.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

- 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).

- 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.
