functions from the analyzer's perspective but not the compiler's.

de-serialization of abstract syntax trees.

PCH support serializes the contents of the abstract syntax tree (AST)
to a bitstream. When the PCH file is read, declarations are serialized
as-needed. For example, a declaration of a variable "x" will be
deserialized only when its VarDecl can be found by a client, e.g.,
based on name lookup for "x" or traversing the entire contents of the
owner of "x".

This commit provides the framework for serialization and (lazy)
deserialization, along with support for variable and typedef
declarations (along with several kinds of types). More
declarations/types, along with important auxiliary structures (source
manager, preprocessor, etc.), will follow.

simplifies the calling interface to clients.

StoredDeclsMap, instead of using the it's-an-array-or-its-a-map
trick. I'll verify that performance isn't impacted later; for now, I
need the common representation.

"manager of symbolic values", wrapping BasicValueFactory, SymbolManager, and
MemRegionManager. While these individual managers nicely separate functionality
in the analyzer, constructing symbolic values can sometimes be cumbersome
because it requires using multiple managers at once. The goal of this class is
to create some factory methods to create SVals that require the use of these
different managers, thus (hopefully) simplifying the analyzer API for clients.
