parenthesized, unlike in C++, e.g.,
C has: typeof ( expression)
C++ has: typeof unary-expression
So, once we've parsed a parenthesized expression after typeof, we
should only go on to parse the postfix expression suffix if we're in
C++. Fixes <rdar://problem/8237491>.

the decls. This was just an oversight before; one we didn't
catch because lots of information in a DeclStmt was also being
traversed (redundantly) elsewhere.
Once DeclStmt was cleaned up, I could clean up some of the
redundant traversals found elswhere as well -- in particular,
traversing the declarations inside a function as part of the
function callback (instead of as part of the CompoundExpr
callback that constitutes the body of the function). The old
way was really weird, and led to some parts of local variable
declarations (but not all) being visited twice. That is now
resolved. I also was able to simplify the traversers for
IfStmt/WhileStmt/etc, which used to have redundant calls to
work around the fact DeclStmt wasn't working properly.
While in the area, I fixed up a few more recursion-ordering
issues. I try to hold to the principle that
RecursiveASTVisitor visits objects in the source code in the
same order they're typed. So the return-type of a variable
comes before the variable-name. This still isn't perfect, but
we're closer to that.

code but Doug keeps fixing stuff!

DeclIsRequiredFunctionOrFileScopedVar.
This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also
needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes.
This fixes current (and avoids future) codegen-from-PCH bugs.

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>).

- 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.
