GRState:
...
- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead).
- GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses
with data elements stored into the GDM.
- Refactor pretty-printing of states to use GRState::Printer objects
exclusively. This removed a huge amount of pretty-printing logic from
GRExprEngine.
CFRefCount
- Simplified some API calls based on refinements to the GDM api.

Removed CheckerState from GRState.
Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.
Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.

* Remove isInSystemHeader() from DiagClient, move it to SourceManager
...
* Move FormatError() from TextDiagnostic up to DiagClient, remove now
empty class TextDiagnostic
* Make DiagClient optional for Diagnostic
This fixes the following problems:
* -html-diags (and probably others) does now output the same set of
warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on
TextDiagnostic
* some code duplication is removed

Added AssumeSymGT, AssumeSymGE, AssumeSymLT, AssumeSymLE to add some minor improvements to path-sensitivity. Right now we basically treat 'x > y' and 'x < y' as implying 'x != y', but this restriction will only inevitably apply to our must rudimentary value tracking component (we'll implement more advanced value reasoning later).
