Chris Lattner 9b65551d0b Generalize RValue to handle complex better, generalize EmitCompoundStmt to 
support any sort of expr, add a new EmitAnyExpr routine.

Chris Lattner c5e940fa55 Implement codegen support for lowering "library builtins" like __builtin_isinf 
to their corresponding library routines (e.g. isinf).  This allows us to handle
all the stuff in macos math.h, and other stuff as it's added to *Builtins.def.

Steve Naroff fb22d96692 Fix the following redefinition errors submitted by Keith Bauer... 
[dylan:~/llvm/tools/clang] admin% cat tentative_decls.c 
// incorrectly generates redefinition error
extern int array[3];
int array[3];

// incorrectly generates a redefinition error
extern void nup(int a[3]);
void nup(int a[3]) {}

It turns out that this exposed a fairly major flaw in the type system,
array types were never getting uniqued! This is because all array types
contained an expression, which aren't unique.

To solve this, we now have 2 array types, ConstantArrayType and
VariableArrayType. ConstantArrayType's are unique, VAT's aren't.

This is a fairly extensive set of fundamental changes. Fortunately,
all the tests pass. Nevertheless, there may be some collateral damage:-)
If so, let me know!

Chris Lattner b6ef18a2b0 Split complex arithmetic codegen out from aggregate codegen. 
This means that we get rid of tons of intermediate allocas.  For
example:

void foo(double _Complex a, double _Complex b) {
   a = b+a+a;
}

this used to have 4 temporary allocas, now it has zero of them.
This also simplifies the individual visitor methods because they
now can all operate on real/imag pairs instead of having to 
load/store all over the place.

Ted Kremenek 2324512285 Modified ArraySubscriptExpr to have accessors getLHS and getRHS in addition 
to getBase and getIdx.  getBase and getIdx now return a "normalized" view
of the expression (e.g., always "A[4]" instead of possibly "4[A]").  getLHS
and getRHS return the expressions with syntactic fidelity to the original
source code.

Also modified client code of ArraySubscriptExpr, including the AST dumper
and pretty printer, the return-stack value checker, and the LLVM code
generator.

Chris Lattner 883f6a7cc7 start splitting out aggregate value computation from EmitExpr into EmitAggExpr. 
aggregate value and scalar expression computation are very different, this
gets them away from each other.  This causes a temporary regression on some
complex number examples.
