Steve Naroff b8ea4fb8db More changes related to implementing ImplicitCastExpr. 
- Fixed a recent regression discovered by Keith Bauer (thanks!). 
The fix involved adding (back) two arguments to UsualArithmeticConversions.
Without the reference arguments, no unary conversions were being passed back
to the caller. This had the effect of turning off the UsualUnaryConversions.
- Refactored CheckAssignmentConstraints into 3 functions. CheckAssignmentConstraints,
CheckSingleAssignmentConstraints, and CheckCompoundAssignmentConstraints. 
- Changed the argument type of DefaultFunctionArrayConversion from QualType->Expr*&.
- Removed a bunch of casts in routines I was working on (cleanup).
- Fixed the visitor for ImplicitCastExpr (oops).

Owen Anderson d975efab16 Handle GEPs with all-zero indices in the same way we handle pointer-pointer bitcasts. Also, fix a potentia infinite loop. 
This brings FastDSE to parity with old DSE on 175.vpr.

Owen Anderson 9c9ef21432 Be more aggressive in removing dead stores, and in removing instructions trivially dead after DSE. 
This drastically improves the effect of FastDSE on kimwitu++.

Steve Naroff 7a5af78270 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.

Gabor Greif f307d942ec * llvm.spec.in: update blurb 
* autoconf/AutoRegen.sh: use variables for autofoo versions
* autoconf/configure.ac: test for some more functions
                         that are not guaranteed on solaris

Note: the svn:mime-type of autoconf/AutoRegen.sh
      should be set to something that allows for
			text compares using svn diff

Steve Naroff 1c8b7d36e6 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;
           ^
