An important, but truly mind numbing change.
Added 6 flavors of Sema::Diag() that take 1 or two SourceRanges. Considered
adding 3 flavors (using default args), however this wasn't as clear.
Removed 2 flavors of Sema::Diag() that took LexerToken's (they weren't used).
Changed all the typechecking routines to pass the appropriate range(s).
Hacked the diagnostic machinery and driver to acccommodate the new data.
What's left? A FIXME in clang.c to use the ranges. Chris offered to do the
honors:-) Which includes taking us to the end of an identifier:-)

Two bug fixes to CheckIncrementDecrementOperand:
- removed "constantOne" usage and simply use Context.IntTy.
- fix the last constraint check...the lvalue test needs to be on the
expression, not the type! (duh).

- Unified CheckSimpleAssignmentOperands/CheckCompoundAssignmentOperands
into one function, named CheckAssignmentOperands. One less function to maintain.
- Converted the unary check functions (ParseUnaryOp and friends) to have
the same API as their binary counterparts.
- Implemented CheckIndirectionOperand (was stubbed). While testing, noticed
that Expr::isModifiableLvalue was incomplete (fixed and referenced draft).
- Added constantOne instance variable to Sema.
- Removed CheckArithmeticOperand (the code was so simple that it is now
part of ParseUnaryOp). The name wasn't great anyway:-)

-Changed the name of TypeRef to QualType. Many diffs.
-Changed the QualType constructor to require Quals be passed. This makes the code a bit
more verbose, however will make the code easier to work on. Given the complexity
of types, this should help spot bogosities.
-Changed the Expr constructor to require a QualType. Same motivation.

Implement ++/-- typechecking for pre/post unary expressions. This includes:
- added isLvalue, isModifiableLvalue (on TypeRef, Type, and RecordType).
- added isRealType, isRealFloatingType, isComplexType.
- hacked Diag to take a TypeRef (I was sick of writing the 2 line "setup":-)
In addition, this will likely lead to less bugs...I already had written code
that was doing a getAsString on "Type" (which is wrong...since it doesn't include
any qualifiers).
- Changed UnaryOperator to take a TypeRef...pass it the right stuff.
- Removed redundant ternary expressions in several predicates.
- A couple diagnostics.

Type Checking...round 2. This checkin "breaks" parsing carbon.h. I imagine
that this will be true for the next week or so. Nevertheless, this round of
changes includes the following:
- Hacked various Expr classes to pass the appropriate TypeRef. Still have
a few more classes to touch.
- Implement type checking for ParseArraySubscriptExpr and ParseMemberReferenceExpr.
- Added a debug hook to derive the class name for Stmt/Expr nodes. Currently a
linear search...could easily optimize if important.
- Changed the name of TaggedType->TagType. Now we have TagType and TagDecl (which
are easier to remember).
- Fixed a bug in StringLiteral conversion I did a couple weeks ago. hadError was
not initialized (oops).
- changed Sema::Diag to return true. This streamlines the type checking code
considerably.
- Added many diagnositics.
This should be it!

More code to parse numeric constants. This checkin includes:
- Feedback from Chris.
- Support for parsing floating point constants.
- Moved the code to "Sema". Changed API in Action.
- More/better error diagnostics.
At this point, the parsing support should be largely complete. Next step
is to work on filling in sensible values (in IntegerLiteral/FloatLiteral).

it to Sema/ASTStreamer (separating the lifetime of ASTContext from
the lifetime of Sema). One day it might be useful to consider creating
a context object implicitly if one isn't provided (using default arguments in
Sema's constructor). At this point, adding this convenience isn't necessary.

the prerocessor will be available via ASTContext).
- Removed the public data member "PP" in ASTContext.
- Changed ASTContext's contructor to take TargetInfo/IdentifierTable explicitly.
- Implicitly create an ASTContext in Sema's constructor. This simplifies
the clients job (and makes ASTContext more private).
--As a side effect, added a "PrintStats" hook to Sema.
To support this level of encapsulation, ASTContext is always dynamically
allocated (by Sema). Previously, ASTContext was being allocated on the
stack. I don't believe this should be a performance issue (since ASTContext
is fairly course grain and tied to the lifetime of Sema currently).

fundamentally requires having an AST around, so move all sema to the
AST library. This is the first step, later steps will be needed to
clean up libast.
