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).

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.

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
