In that case a chained PCH will record the updates to the DefinitionData pointer of forward references.
If a forward reference mutated into a definition re-write it into the chained PCH, this is too big of a change.

Introduce a DeclsToRewrite field in ASTWrite, used for collecting the decls that will be replaced in the chained PCH.

- Pass around RecordDataImpl instead of the concrete RecordData so that any SmallVector can be used.
- Move ASTDeclWriter::WriteCXXDefinitionData to ASTWriter::AddCXXDefinitionData.

its initial creation/deserialization and store the changes in a chained PCH.

The idea is that the AST entities call methods on the ASTMutationListener to give notifications
of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP

Simplify and "robust-ify" the way that CXXRecord references point to the definition data when loaded from PCH.

Temporary disable 'test/PCH/chain-cxx.cpp' until a better way to fix it is in place.

it isn't unreachable and should not be zapped.  The check for the entry block
was missing in one case: a block containing a unwind instruction.  While there,
do some small cleanups: "M" is not a great name for a Function* (it would be
more appropriate for a Module*), change it to "Fn"; use Fn in more places.

- Fixed test cases for unreachable code warnings produced by Sema.

Previously the post-RA schedulers completely ignore these dependencies since
returns, branches, etc. are all scheduling barriers. This patch model the
latencies between instructions being scheduled and the barriers. It also
handle calls by marking their register uses.
