Removed Attr.[h,cpp]...they didn't have any useful content.

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...

Two vector fixes:

- Sema::CheckAssignmentConstraints() needs to compare the canonical type.
- Expr::isLvalue() needs to disallow subscripting into a vector returned by a function. This
follows the rules for struct returns (in C, at least...C++ is another story:-)

Here is an example...

float4 float4_return()
{
    float4 xx;

    return xx;
}
void add_float4_void_return(float4 *a, float4 *b, float4 *result)
{
    float f;
    float4_return()[1] = f; // now illegal
}

Not having this prevented promoting float arguments to double when passed
into printf, for example.

Typechecking support for vectors...

- Added CheckVectorOperands(). Called from CheckAdditionOperands,

- Added diagnostic for converting vector values of different size.
- Modified Type::isArithmeticType to include vectors.

Sould be ready for Chris to add code generation. I will continue testing/refining.

- Finished semantic analysis for vectors, added some diagnostics.
- Added AST for vectors (instantiation, installation into the decl).
- Fixed bug in ParseArraySubscriptExpr()...this crasher was introduced by me
when we added the range support.
- Turned pedantic off by default. Since vectors are gcc extensions, having
pedantic on by default was annoying. Turning it off by default is  also
consistent with gcc (but this wasn't my primary motivation).
- Tweaked some comments and diagnostics.

Note: The type checking code is still under construction (for vectors). This
will be my next check-in.

- Fix for C++ casting operators failing during parsing. Deriving the C++ cast
  expressions from CastExpr was the wrong way to go. Its constructor creates
  null QualTypes in one of its constructors. This doesn't work well with how
  the C++ casting expression class wanted to do things. Derive just from Expr
  instead.
