such that every declaration ID loaded from an AST file will go through
a central local -> global mapping function. At present, this change
does nothing, since the local -> global mapping function is the
identity function.
This is the mechanical part of the refactoring; a follow-up patch will
address a few remaining areas where it's not obvious whether we're
dealing with local or global IDs.

entities generated directly by the preprocessor from those loaded from
the external source (e.g., the ASTReader). By separating these two
sets of entities into different vectors, we allow both to grow
independently, and eliminate the need for preallocating all of the
loaded preprocessing entities. This is similar to the way the recent
SourceManager refactoring treats FileIDs and the source location
address space.
As part of this, switch over to building a continuous range map to
track preprocessing entities.

the AST reader down to the AST file + local ID, rather than walking
the PCH chain. More cleanup/generalization, although there is more
work to do for preprocessed entities. In particular, the
"preallocation" scheme for preprocessed entities is not going to work
well with late loading of PCH files, and it's likely we'll have to do
something akin to the SourceManager's negative/positive loading.

source locations from source locations loaded from an AST/PCH file.
Previously, loading an AST/PCH file involved carefully pre-allocating
space at the beginning of the source manager for the source locations
and FileIDs that correspond to the prefix, and then appending the
source locations/FileIDs used for parsing the remaining translation
unit. This design forced us into loading PCH files early, as a prefix,
whic has become a rather significant limitation.
This patch splits the SourceManager space into two parts: for source
location "addresses", the lower values (growing upward) are used to
describe parsed code, while upper values (growing downward) are used
for source locations loaded from AST/PCH files. Similarly, positive
FileIDs are used to describe parsed code while negative FileIDs are
used to file/macro locations loaded from AST/PCH files. As a result,
we can load PCH/AST files even during parsing, making various
improvemnts in the future possible, e.g., teaching #include <foo.h> to
look for and load <foo.h.gch> if it happens to be already available.
This patch was originally written by Sebastian Redl, then brought
forward to the modern age by Jonathan Turner, and finally
polished/finished by me to be committed.

to allow clients to specify that they've already (correctly) loaded
declarations, and that no further action is needed.
Also, make sure that we clear the "has external lexical declarations"
bit before calling FindExternalLexicalDecls(), to avoid infinite
recursion.

Also add the missing serialization support for SEHTryStmt,
SEHFinallyStmt, and SEHExceptStmt, and fix and finish the
serialization support for AsTypeExpr. In addition, change
the code so that it will no longer link if a Stmt subclass
is missing serialization support.

but at least it doesn't have a redundant QualType and a broken
children() method.
Noticed this while doing things in serialization.

This should improve source fidelity, as well as being generically
useful for diagnostics and such.
