template partial specializations are not permitted at all, but that seems like
an obvious wording defect, and if we allow them without a nested name specifier
we should also allow them with a nested name specifier.

Before the patch, -fprofile-instr-generate compile will fail
if no integrated-as is specified when the file contains
any static functions (the -S output is also invalid).

This patch fixed the issue. With the change, the index format
version will be bumped up by 1. Backward compatibility is

Make RedirectedFileSystem::openFilForRead(path)->status() the same as
RedirectedFileSystem::status(path). Previously we would just get the
status of the underlying real file, which would not have the IsVFSMapped
bit set.

This fixes rebuilding a module that has an include that is relative to
the includer where we will lookup the real path of that file before we
lookup the VFS location.

This works around existing system headers which unconditionally
redefine these macros.

This is reasonably safe to do because we used to warn about it anyway
(outside of system headers).  Continue to warn if the redefinition
would have changed the expansion.  Still permit redefinition if the
macro is explicitly #undef'ed first.

Objective-C properties: merge attributes when redeclaring 'readonly' as 'readwrite' in an extension.

r251874 stopped back-patching the AST when an Objective-C 'readonly'
property is redeclared in a class extension as 'readwrite'. However,
it did not properly handle merging of Objective-C property attributes
(e.g., getter name, ownership, atomicity) to the redeclaration,
leading to bad metadata. Merge (and check!) those property attributes
so we get the right metadata and reasonable ASTs. Fixes

Teach DeduceFromInitializerList in SemaTemplateDeduction.cpp to deduce against array (constant and dependent sized) parameters (really, reference to arrays since they don't decay to pointers), by checking if the template parameter is either one of those kinds of arrays, and if so, deducing each initializer list element against the element type, and then deducing the array bound if needed.

In brief, this patch enables the following code:
template<class T, int N> int *f(T (&&)[N]);
int *ip = f({1, 2, 3});
