For TagType and TemplateSpecializationType, isDependent calculation may be invalid because some decls that the
...
calculation is using may still be initializing.
Thus, store the isDependent flag to PCH and restore directly to Type.

fix the clang side of PR7437: EmitAggregateCopy

A using declaration can redeclare a typedef to the same type. These

Added a path-sensitive idempotent operation checker (-analyzer-idempotent-operation). Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect.
...
Example:
{
int a = 1;
int b = 5;
int c = b / a; // a is 1 on all paths
}
- New IdempotentOperationChecker class
- Moved recursive Stmt functions in r107675 to IdempotentOperationChecker
- Minor refactoring of SVal to allow checking for any integer
- Added command line option for check
- Added basic test cases
