b3b0b8034c Fix/Improve SourceRange of explicitly defaulted members
When adding the implicit compound statement (required for Codegen?), the
end location was previously overridden by the start location, probably
based on the assumptions:

* The location of the compound statement should be the member's location
* The compound statement if present is the last element of a FunctionDecl

This patch changes the location of the compound statement to the
member's end location.

d4a3f0e894 Hide the concept of diagnostic levels from lex, parse and sema
The compilation pipeline doesn't actually need to know about the high-level
concept of diagnostic mappings, and hiding the final computed level presents
several simplifications and other potential benefits.

The only exceptions are opportunistic checks to see whether expensive code
paths can be avoided for diagnostics that are guaranteed to be ignored at a
certain SourceLocation.

This commit formalizes that invariant by introducing and using
DiagnosticsEngine::isIgnored() in place of individual level checks throughout
lex, parse and sema.

5ef4fe7d8e MS ABI: Fix inheritance model calculation in CRTP
CRTP-like patterns involve a class which inherits from another class
using itself as a template parameter.

However, the base class itself may try to create a pointer-to-member
which involves the derived class.  This is problematic because we
may not have finished parsing the most derived classes' base specifiers
yet.

It turns out that MSVC simply uses the unspecified inheritance model
instead of doing anything fancy.

This fixes PR19987.

6713086bca Check the access of operator delete from the destructor context
Previously we would do the access check from the context of
MarkVTableUsed.

Also update this test to C++11, since that is typically used with the MS
C++ ABI.

e8ad3839a1 Don't inherit dllimport to inline move assignment operators
Current MSVC versions don't have move assignment operators, so we
can't rely on them being available in the dll. If we have the
definition, we can just use that directly. This breaks pointer
equality, but should work fine otherwise.

When there is an MSVC version that supports move assignment,
we can key this off the -fmsc-ver option.

853ae94660 Start adding support for dllimport/dllexport on classes (PR11170)
This implements the central part of support for dllimport/dllexport on
classes: allowing the attribute on class declarations, inheriting it
to class members, and forcing emission of exported members. It's based
on Nico Rieck's patch from http://reviews.llvm.org/D1099.

This patch doesn't propagate dllexport to bases that are template
specializations, which is an interesting problem. It also doesn't
look at the rules when redeclaring classes with different attributes,
I'd like to do that separately.

04e2e665cb Don't emit -Wnon-virtual-dtor on final classes, since it's not a problem there.
The base class is the culprit/risk here - a sealed/final derived class
with virtual functions and a non-virtual dtor can't accidentally be
polymorphically destroyed (if the base class's dtor is protected - which
also suppresses this warning).

d78f92fbb2 Rewrite NRVO determination. Track NRVO candidates on the parser Scope and apply the NRVO candidate flag to all possible NRVO candidates here, and remove the flags in computeNRVO or upon template instantiation. A variable now has NRVO applied if and only if every return statement in that scope returns that variable. This is nearly optimal.
Performs NRVO roughly 7% more often in a bootstrap build of clang. Patch co-authored by Richard Smith.

83e78f5c3c Fix handling of redeclaration lookup for using declarations, where the prior
declaration is not visible. Previously we didn't find hidden friend names in
this redeclaration lookup, because we forgot to treat it as a redeclaration
lookup. Conversely, we did find some local extern names, but those don't
actually conflict with a namespace-scope using declaration, because the only
conflicts we can get are scope conflicts, not conflicts due to the entities
being members of the same namespace.
