Change name of -sched option and DEBUG_TYPE to
pre-RA-sched; adjust testcases.

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.

* 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

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.

Remove the end-block handling code.  It was unsafe, and making it safe would have resulted in falling back to the slow DSE case.  I need to think some more about the right way to handle this.

following jump tables that it earlier inserted.  This
would be OK on other targets but is needed for correctness
only on ARM (constant islands needs to find jump tables).
