assert is now done in UsualUnaryConversions().

Add (explicit) AST support for implicit casts. This should simplify the 
code generator. Source translation tools can simply ignore this node.

- Added a new Expr node, ImplicitCastExpr.
- Changed UsualUnaryConversions/UsualArithmeticConversions to take references 
to Expr *'s. This will allow these routines to instantiate the new AST node
and pass it back.
- Changed all clients of UsualUnary/UsualArithmetic (lot's of diff's).
- Changed some names in CheckConditionalOperands. Several variables where
only distinguished by their case (e.g. Cond, cond). Yuck (what was I thinking).
- Removed an old/crufty constructor in CastExpr (cleanup).

This check-in does not actually create the new AST node. I wanted to separate
the mechanical changes from the semantic changes. In addition, I need to 
coordinate with Chris, since the semantic change will break the code generator.

Both in one patch, and the test case that Chris didn't commit last
time is in there too...

I'll split the patch up if somebody wants it split."

I've added a tests/CodeGen directory, and a test for this case that
used to fail and now passes."

Two changes...

- Teach all the integer/float predicates on Type about Vectors.
- Disallow bitwise compliment on float vectors. For example...

typedef float __attribute__(( vector_size(16) )) float4;

float4 float4_return()
{
    float4 xx;

    return ~xx;
}

...now emits the following diagnostic...

[administrators-powerbook59:~/llvm/tools/clang] admin% ../../Debug/bin/clang bug.c
bug.c:8:12: error: invalid argument type to unary expression 'float4'
    return ~xx;
           ^
1 diagnostic generated.

When more (GCC) attributes are added, we might want to create a file
of this ilk. For now, it's better to remove them (to eliminate any confusion).

I also update the Xcode project file...
