Change encoding of TokenKind in IdentifierTable to be of type "unsigned"
...
instead of TokenKind because of signedness issues with MSVC and enums.
Patch from Argiris Kirtzidis.

Patch from Argiris Kirtzidis:
...
The patch fixes some debug assertions that the msvcrt throws:
1)
- if (isprint(value) && value < 256) {
+ if (value < 256 && isprint(value)) {
isprint() does an assertion check of its own for value < 256; check value before calling it to prevent it.
2)
- Stmt->Names.push_back(std::string(&data[0], data.size()));
+ if (data.size() == 0)
+ Stmt->Names.push_back(std::string());
+ else
+ Stmt->Names.push_back(std::string(&data[0], data.size()));
If data.size() == 0 then data[0] throws "out of range" assertion.

Major cleanup of path-sensitive analysis engine and the current analysis
...
based on constant. prop. and limited symbolics.
- Renamed class: RValue -> RVal, LValue -> LVal, etc.
- Minor method renamings and interface cleanups.
- Tightened the RVal "type system" so that UninitializedVal and UnknownVal
cannot be cast to LVal or NonLVal. This forces these corner cases values
to be explicitly handled early before being dispatched to plug-in transfer
function logic.
- Major cleanup in the transfer function logic for binary and unary operators.
Still fixing some regressions, but we now explicitly handle Uninitialized
and Unknown values in a more rigorous way.
