3084a61e98 -Make TokenID of IdentifierInfo read-only, remove setTokenID(). 
-There are 2 instances that change the TokenID for GNU libstdc++ 4.2 compatibility.
  To handler those cases introduce a RevertedTokenID bitfield, RevertTokenIDToIdentifier() and hasRevertedTokenIDToIdentifier() methods.
  Store the bitfield in PCH.

1c28331b57 Speculatively revert r110610 " Make ObjCInterfaceDecl redeclarable, 
and create separate decl nodes for forward declarations and the
definition," which appears to be causing significant Objective-C
breakage.

ab6a088314 - Make ObjCInterfaceDecl redeclarable, and create separate decl nodes for forward declarations and the definition. 
- Eagerly create ObjCInterfaceTypes for declarations.
- The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another.
- Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated.

839bbacfb2 Apart from storing/retrieving the previous redeclaration from PCH, also store/retrieve the most recent 
redeclaration. That way we are sure that the full redeclarations chain is loaded.

When using chained PCHs, first declarations point to the most recent redeclarations in the same PCH.
To address this use a REDECLS_UPDATE_LATEST record block to keep track of which first declarations need
to point to a most recent redeclaration in another PCH.

78f5177d37 Query only the latest version of an identifier in the PCH chain. Make sure this version holds the entire declaration chain. This is a much saner solution than trying to merge the info from all elements, and makes redeclarations work properly. Expand the declarations test case to cover more compliated cases.

b24355af87 Refactor the way PCHReader tracks whether we are in recursive loading. 
-Replace CurrentlyLoadingTypeOrDecl with a counting scheme (NumCurrentElementsDeserializing)
-Provide outside access to the mechanism by adding methods StartedDeserializing/FinishedDeserializing
  to ExternalASTSource.

These are preparation for the next commit.

07a89a83d4 Make macro weirdness in chained PCH work. This required changing the way PCHReader and PCHWriter are initialized to correctly pick up all initializer. On the upside, this means that there is far less repetition in the dependent PCH now.

ce3a8293a0 Implement -fno-validate-pch at the -cc1 level, which suppresses most 
of the usual consistency checks used to determine when a precompiled
header is incompatible with the translation unit it's being loaded
into.

Enable this option when loading a precompiled preamble, because the
preamble loader will be performing all of this checking itself. Enable
the preamble-based test now that it's working.

This option is also useful for debugging Clang's PCH
(<rdar://problem/7532213>).

66c5eef182 - Fix recording of offsets of types in dependent PCHs. 
- Stop reading in (and thus deserializing) every declaration in the TU when creating a dependent PCH.
- Switch the storage of a decl context's lexical declarations to a blob containing the IDs instead of a record. This is the only sane way of supporting update records later on.

85b2a6a430 Add a callback interface that allows interested parties to get notified whenever PCHReader deserializes a type or decl (and possibly other things in the future). Have PCHWriter implement these callbacks as noops and register to receive them if we're chaining PCHs. This will allow PCHWriter to track the IDs of these things, which it needs to write the dependent files. WIP
