We model predefined declarations as not being from AST files, but in most ways
they act as if they come from some implicit prebuilt module file imported
before all others. Therefore, if we see an update to the predefined 'struct
__va_list_tag' declaration (and we've already loaded any modules), it needs a
corresponding update record, even though it didn't technically come from an AST
file.

It seems (I guess) in ObjC that va_list is provided without the need for
inclusions. I verified that with this change the test still crashes in
the absence of the fix committed in r217275.

This innocuous statement to get the identifier info for __va_list_tag
was causing an assertion failure:
NextIsPrevious() && "decl became non-canonical unexpectedly"
if the __va_list_tag identifier was found in a PCH in some
circumstances, because it was looked up before the ASTReader had a Sema
object to use to find existing decls to merge with.
We could possibly move getting the identifier info even later, or make
it lazy if we wanted to, but this seemed like the minimal change.
Now why a PCH would have this identifier in the first place is a bit
mysterious. This seems to be related to the global module index in some
way, because when the test case is built without the global module index
it will not emit an identifier for __va_list_tag into the PCH, but with
the global module index it does.
