emit lexical contents for a declaration for another module. Track which module
those contents came from, and ensure that we only grab the lexical contents
from a single such instantiation.

determining whether a declaration is out of line, instead of assuming
that the semantic and lexical DeclContext will be the same declaration
whenever they're the same entity.
This fixes behavior of declarations within merged classes and enums.

members from all redefinitions of a class that have them, in case the special
member is defined in one module but only declared in another.

member functions), ensure that the redecl chain never transitions from 'inline'
to 'not inline', since that violates an AST invariant.

This fixes a bug where an update record causes us to load an entity that refers
to an entity we've not finished loading yet, resulting in badness.
llvm-svn: 207603
after we've already instantiated a definition for the function, pass it to the
ASTConsumer again so that it knows the specialization kind has changed and can
update the function's linkage.
This only matters if we instantiate the definition of the function before we
reach the end of the TU; this can happen in at least three different ways:
C++11 constexpr functions, C++14 deduced return types, and functions
instantiated within modules.

This change doesn't go all the way to making fields redeclarable; instead, it
makes them 'mergeable', which means we can find the canonical declaration, but
not much else (and for a declaration that's not from a module, the canonical
declaration is always that declaration).
llvm-svn: 192092
it is an implicit instantiation of a class template specialization), pick the
first-loaded definition to be the canonical definition, and merge all other
definitions into it.
This is still rather incomplete -- we need to extend every form of declaration
that can appear within a CXXRecordDecl to be redeclarable if it came from an
AST file (this includes fields, enumerators, ...).
llvm-svn: 190315
This is especially relevant for templatedDecls that might be injected (and thus have their DeclContext set to) somewhere completely different.

Check whether a pending instantiation needs to be instantiated (or whether an instantiation already exists).
Verify the size of the PendingInstantiations record (was only checking size of existing PendingInstantiations).
Migrate Obj-C++ part of redecl-merge into separate test, now that this is growing.
templates.mm: test that CodeGen has seen exactly one definition of template instantiations.
redecl-merge.m: use "@" specifier for expected-diagnostics.
