Don't use * in XFAIL line unless you want it to XFAIL on everything. I don't believe you can use true regular expressions here. It will just look for those keywords. Please test this on sparc and see if they still are xfailed.

Missed the case where alloca is used but the stack size (not including callee-saved portion) is zero. Thanks Dan.

Move tests that have C/C++ sources into the appropriate directory. This
allows them to be selected for testing based on whether llvm-gcc is
present or not.

Change dyn_cast for reference types to be more like pointers and not need the canonical type. Also fix so that we're not expecting a return value from a void function

    According to the spec (C++ 5p6[expr]), we need to adjust "T&" to
    "T" before further analysis. We do this via the "implicit cast"
    thingy.

Convert UsualArithmeticConversions to return "void". Now that we synthesize ImplicitCastExpr's,
there is no compelling need to return the converted type. If both expression type's are arithmetic, then
both types will always be the same. If they aren't (for pointer/int types, say), then the
types will be different. The client is responsible for distinguishing...

Remove the 2 QualType references to method UsualArithmeticConversions. Last week, I added these
to quickly fix a regression. Avoiding them entirely is a much cleaner solution. Clients of 
UsualArithmeticConversions should simply call getType() on the expression to get the
converted type. In practice, only a small number of routines care about this.

This also avoids a fork bomb from the llvm-top/build script which
doesn't know how to handle cycles in the dependence graph.

isPointerType and isVectorType to only look through a single level of typedef
when one is present.  For this invalid code:

typedef float float4 __attribute__((vector_size(16)));
typedef int int4 __attribute__((vector_size(16)));
typedef int4* int4p;
void test(float4 a, int4p result, int i) {
    result[i] = a;
}

we now get:

t.c:5:15: error: incompatible types assigning 'float4' to 'int4'
    result[i] = a;
    ~~~~~~~~~ ^ ~

instead of:

t.c:5:15: error: incompatible types assigning 'float4' to 'int  __attribute__((vector_size(16)))'
    result[i] = a;
    ~~~~~~~~~ ^ ~

The rest of the type predicates should be upgraded to do the same thing.

Change DefaultFunctionArrayConversions and UsualUnaryConversions to return void. The caller 
needs to query the expression for the type. Since both these functions guarantee the expression 
contains a valid type, removed old/vacuous asserts (from code calling both of these routines).

ConstantFoldBinaryFP and use it for all binary floating-point operations
which may have an error. These functions still rely exclusively on errno
to detect errors though.
