ARM & AArch64: unify the rest of the completely shared NEON implementations
This should be the last routine patch: AArch64 does still delegate to
EmitARMBuiltinExpr, but the remaining instances have complications of
one sort or another so some more cunning thought will be needed.

Fix autolinking when modules are imported in pch files
Add the ImportDecl to the set of interesting delcarations that are
deserialized eagerly when an AST file is loaded (rather than lazily like
most decls). This is required to get auto linking to work when there is
no explicit import in the main file. Also resolve a FIXME to rename
'ExternalDefinitions', since that is only one of the things that need eager
deserialization. The new name is 'EagerlyDeserializedDecls'. The corresponding
AST bitcode is also renamed.

Diagnose typedef names for linkage purposes that would change
a previously-computed linkage as an unsupportable error condition.
Per discussion on cfe-commits, this appears to be a
difficult-to-resolve flaw in our implementation approach;
we may pursue this as a language defect, but for now it's
better to diagnose it as unsupported than to produce
inconsistent results (or assertions). Anything that we can
do to limit how often this diagnostic fires, such as the
changes in r200380, is probably for the best, though.

Short-circuit a couple of queries (and avoid corrupting

There's a very deep problem here where the linkage of
a declaration can suddenly massively change as soon as
it's given a typedef name; these fixes, while optimizations
in their own right, are really just targeted workarounds.

It also sets a bit on the spelling certifying that it is known to GCC. From this, we can warn about the extension appropriately.

Enforce safe usage of DiagnosticsEngine::getCustomDiagID()
Replace the last incorrect uses and templatize the function to require a

The diagnostic formatter expects well-formed input and has undefined behaviour
with arbitrary input or crafted user strings in source files. Accepting user
input would also have caused unbounded generation of new diagnostic IDs which
can be problematic in long-running sessions or language bindings.
This completes the work to fix several incorrect callers that passed user
input or raw messages to the diagnostics engine where a constant format string
was expected.
