Update several tests to explicitly use BasicConstraintManager as well as to use RangeConstraintManager with RegionStoreManager.

- now logs which source files had "ignored attributes".
- disable-free is enabled

scan-build:
- now displays a table of ignored attributes under "Analyzer Failures".

specialization of class templates, e.g.,

  template<typename T> class X;

  template<> class X<int> { /* blah */ };

Each specialization is a different *Decl node (naturally), and can
have different members. We keep track of forward declarations and
definitions as for other class/struct/union types.

This is only the basic framework: we still have to deal with checking
the template headers properly, improving recovery when there are
failures, handling nested name specifiers, etc.

 - Renamed to getDeclAlignInBytes since most other query functions
   work in bits.

 - Fun to track down as isIntegerConstantExpr was getting it right,
   but Evaluate() was getting it wrong. Maybe we should assert they
   compute the same thing when they succeed?

Enhance tests to exercise more combinations of using the RangeConstraintManager with the RegionStoreManager.

Zhongxing Xu. The resultant code is less than 1/2 the size of the original.

Key highlights:

- All CouldBeXXX methods have been removed. Checking for feasibility is now just
  done in the AddXXX methods.

- RangeSets now represent "all possible values" explicitly as the range set {
  [min, max] } instead of the empty set. The empty set now represents "no
  feasible values". This change consolidated much of the core algorithm to only
  have one code path instead of alternate paths that considered the empty set to
  represent "all possible falues."

IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.
