In the ASTReader, factor out the loading of (local) declaration IDs,
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.
Cleaning up more of the ID situation in the AST reader. This patch relaxes and generalizes how CXX base specifiers are identified and loaded by using a ContinuousRangeMap. This also adds a global bit offset (or base) to the PerFileData.

Rework the detailed preprocessing record to separate preprocessing
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.
Continuing to improve and generalize how IDs are handled in ASTReader. This patch cleans up and generalizes TypeID loading and uses a similar table-lookup to Doug's previous Decl patch.

fix rdar://9780211 - Clang crashes with an assertion failure building WKView.mm from WebKit
This is something of a hack, the problem is as follows:
1. we instantiate both copied of RetainPtr with the two different argument types
(an id and protocol-qualified id).
2. We refer to the ctor of one of the instantiations when introducing global "x",
this causes us to emit an llvm::Function for a prototype whose "this" has type
"RetainPtr<id<bork> >*".
3. We refer to the ctor of the other instantiation when introducing global "y",
however, because it *mangles to the same name as the other ctor* we just use
a bitcasted version of the llvm::Function we previously emitted.
4. We emit deferred declarations, causing us to emit the body of the ctor, however
the body we emit is for RetainPtr<id>, which expects its 'this' to have an IR
type of "RetainPtr<id>*".
Because of the mangling collision, we don't have this case, and explode.
This is really some sort of weird AST invariant violation or something, but hey
a bitcast makes the pain go away.

Revamp the SourceManager to separate the representation of parsed
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.
Reduce -Wuninitialized time by 22% (on sqlite) by removing the recursive AST crawl.
This is accomplished by forcing the needed expressions for -Wuninitialized to always be CFGElements in the CFG.
This allows us to remove a fair amount of the code for -Wuninitialized.
Some fallout:
- AnalysisBasedWarnings.cpp now specifically toggles the CFGBuilder to create a CFG that is suitable for -Wuninitialized. This
is a layering violation, since the logic for -Wuninitialized is in libAnalysis. This can be fixed with the proper refactoring.
- Some of the source locations for -Wunreachable-code warnings have shifted. While not ideal, this is okay because that analysis
already needs some serious reworking.
