None of our tests use /fallback, so this lets us gradually add RTTI

Saleem Abdulrasool 8ab3e83efa CodeGen: support dll{ex,im}port on WoA
Add ARM support for dllexport and dllimport attributes.  This is a relatively
conservative change.  The alternative is to entirely drop the architecture
requirement.  The dllimport and dllexport attributes are not restricted to any
architecture, simply to platforms that support this attribute (currently
Windows).

Fixes PR19689, and possibly the last leak in clang (PR19521). PR19689 contains
a few suggestions on how to make the default argument token code a bit more
solid, these changes can possibly be landed in follow-ups.

Reid Kleckner 37abaca3c2 MS ABI: Pass 'sret' as the second parameter of instance methods
Summary:
MSVC always passes 'sret' after 'this', unlike GCC.  This required
changing a number of places in Clang that assumed the sret parameter was
always first in LLVM IR.

This fixes win64 MSVC ABI compatibility for methods returning structs.

Aaron Ballman 7c192b452f Add the ability to use logical expressions for capability attributes. This is to allow requirements to be expressed not just in terms of lists, but in terms of logical expressions. Eg)
void foo(void) __attribute__((requires_capability((FlightControl || Worker) && !Logger)));

Benjamin Kramer a7bcab75d2 ThreadSafetyAnalysis: Don't crash when trying to analyze objc methods.
The thread safety analysis isn't very useful in ObjC (you can't annotate
ObjC classes or methods) but we can still analyze the actual code and
show violations in usage of C/C++ functions.

Fixes PR19541, which does not use thread safety attributes but crashes
with -Weverything.

Ben Langmuir c95e56488d Switch Wmodule-build to a remark
On reflection, this is better despite the missing command-line handling
bits for remarks.  Making this a remark makes it much clearer that
this is purely informational and avoids the negative connotations of a
'warning'.

Ben Langmuir 46b02e3edd Remove -Wnon-modular-include

This warning is too noisy and doesn't really indicate a problem for most

-Weverything, that seems bad so remove it.

Diego Novillo 6dc9c4814f Fix segmentation fault when mixing -Rpass with #line.
Summary:
When using #line directives, FileManager::getFile() will return a nil
entry. This triggers an assert in translateFileLineCol().

This patch handles nil FileEntry instances by emitting a note that the
location could not be translated back to a SourceLocation. I don't
really like this solution, but we are translating presumed locations,
so some information has already been lost.

Karthik Bhat 967c13d3fb Fix PR19169 [Crash on invalid attempting to specialize a template method as a template variable].
A template declaration of a template name can be null in case we have a dependent name or a set of function templates.
Hence use dyn_cast_or_null instead of dyn_cast. Also improve the diagnostic emitted in this case.

Nico Weber 824285ec53 Let ASTReader optionally delete its ASTDeserializationListener.
Use this to fix the leak of DeserializedDeclsDumper and DeserializedDeclsChecker
in FrontendAction (found by LSan), PR19560.

The "delete this" bool is necessary because both PCHGenerator and ASTUnit
return the same object from both getDeserializationListener() and
getASTMutationListener(), so ASTReader can't just have a unique_ptr.

It's also not possible to just let FrontendAction (or CompilerInstance) own
these listeners due to lifetime issues (see comments on PR19560).

Finally, ASTDeserializationListener can't easily be refcounted, since several of
the current listeners are allocated on the stack.

Having this bool isn't ideal, but it's a pattern that's used in other places in
the codebase too, and it seems better than leaking.

Nico Weber 5f8116ba46 Fix a leak found by LSan: ConsumedBlockInfo owns its StateMapsArray entries.
(I tried converting StateMapsArray to a vector<unique_ptr> and changing the
types of getInfo() and addInfo() to take unique_ptrs.  This mostly worked,
except for the three-argument form of addInfo() which I found confusing enough
that I went with this simpler fix for now.)
