58734db080 [analyzer] Remove getEngine() form CheckerContext
A step toward making sure that diagnostics report should only
be generated though the CheckerContext and not though BugReporter
or ExprEngine directly.

b473816b4a [analyzer] Simplify CheckerContext
Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?

c4a2d3259f Introduce a placeholder type for "pseudo object"
expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

4a2a8f7fb8 Check for unexpanded parameter packs in the name that guards a
Microsoft __if_exists/__if_not_exists statement. Also note that we
weren't traversing DeclarationNameInfo *at all* within the
RecursiveASTVisitor, which would be rather fatal for variadic
templates.

deb4a2be67 Implement support for dependent Microsoft __if_exists/__if_not_exists
statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".

429ec024f8 [PCH] When visiting preprocessed entities, make it possible to avoid deserializing
preprocessed entities that are #included in the range that we are interested.

This is useful when we are interested in preprocessed entities of a specific file, e.g
when we are annotating tokens. There is also an optimization where we cache the last
result of PreprocessingRecord::getPreprocessedEntitiesInRange and we re-use it if
there is a call with the same range as before.

43edb32f1f Rework Microsoft __if_exists/__if_not_exists parsing and semantic
analysis to separate dependent names from non-dependent names. For
dependent names, we'll behave differently from Visual C++:

  - For __if_exists/__if_not_exists at class scope, we'll just warn
    and then ignore them.
  - For __if_exists/__if_not_exists in statements, we'll treat the
    inner statement as a compound statement, which we only instantiate
    in templates where the dependent name (after instantiation)
    exists. This behavior is different from VC++, but it's as close as
    we can get without encroaching ridiculousness.

The latter part (dependent statements) is not yet implemented.

89ab56d5fb When we perform a lookup for a dependent name that is a member of an
unknown specialization, treat this the same way as if the name were
not found in the current instantiation. No actual functionality
change, since apparently nothing depends on this.

cbb407268e Constant expression evaluation: evaluate lvalues as lvalues, and rvalues as

e594034f1f [analyzer] Convert ExprEngine::visit() to use short lived builders.
This commit removes the major functional dependency on the ExprEngine::Builder
member variable.

In some cases the code became more verbose. Particularly, we call takeNodes()
and addNodes() to move responsibility for the nodes from one builder to another.
This will get simplified later on.

To convert iteratively, we take the nodes the local builder will
process from the from the global builder and add the generated nodes
after the short lived builder is done. PureStmtNodeBuilder is the
one we should eventually use everywhere. Added Stmt index and Builder
context as ExprEngine globals. To avoid passing them around.
