Unqualified templated constructors cannot be friended and our lack of a
diagnostic led to violated invariants. Instead, raise a diagnostic when
processing the friend declaration.
This fixes PR20251.

When an Objective-C method implements a protocol requirement, do not
inherit any availability information from the protocol
requirement. Rather, check that the implementation is not less
available than the protocol requirement, as we do when overriding a
method that has availability. Fixes rdar://problem/22734745.

Unscaled load/store combining has been enabled since the initial ARM64 port. No
need for a redundance run. Also, add CHECK-LABEL directives.

Summary:
Given an array of i2 elements, 4 consecutive scalar loads will be lowered to
i8-sized loads and thus will access 4 consecutive bytes in memory. If we
vectorize these loads into a single <4 x i2> load, it'll access only 1 byte in
memory. Hence, we should prohibit vectorization in such cases.
PS: Initial patch was proposed by Arnold.

Part of https://llvm.org/bugs/show_bug.cgi?id=25002
In writing the new process_control test included here,
I discovered that the scenario would hang indefinitely,
bypassing the timeout logic.
This fixes the indefinite hang, converting an error
in the new test to a failure. I'll fix the failure
next. This one was heinous enough to fix on its own,
though.

the corresponding TypeSystem. This makes sense because what kind of data there
is -- and how it can be looked up -- depends on the language.
Functionality that is common to all type systems is factored out into
PersistentExpressionState.

Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.
However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

Previously, the index was constrained to the size of the memory operation for
no apparent reason. This change removes that constraint so that we can form
pre-index instructions with any valid offset.

Same strategy as simplifyInstructionsInBlock. ~1/3 less time
on my test suite. This pass doesn't have many in-tree users,
but getting rid of an O(N^2) worst case and making it cleaner
should at least make it a viable alternative to ADCE, since
it's now consistently somewhat faster.

We get into this bad state when someone defines a new member function
for a class but forgets to add the declaration to the class body.
Calling the new member function from a member function template of the
class will crash during instantiation.

As Richard Barton observed at http://reviews.llvm.org/D12937#inline-107121
TargetParser in LLVM has insufficient support for ARMv6Z and ARMv6ZK.
In particular, there were no tests for TrustZone being supported in these
architectures.
The patch clears a FIXME: left by Saleem Abdulrasool in r201471, and fixes
his test case which hadn't really been testing what it was claiming to test.

This linker script parser and evaluator is powerful enough to read
Linux's libc.so, which is (despite its name) a linker script that
contains OUTPUT_FORMAT, GROUP and AS_NEEDED directives.
The parser implemented in this patch is a recursive-descendent one.
It does *not* construct an AST but consumes directives in place and
sets the results to Symtab object, like what Driver is doing.
This should be very fast since less objects are allocated, and
this is also more readable.

Usually large blocks are not a problem. But if a large block (> 10k instructions)
contains many (potential) chains of vector instructions, and those chains are
spread over a wide range of instructions, then scheduling becomes a compile time problem.
This change introduces a limit for the accumulate scheduling region size of a block.
For real-world functions this limit will never be exceeded (it's about 10x larger than
the maximum value seen in the test-suite and external test suite).

Because we handle more than SCEV does it is not possible to rewrite an
expression on the top-level using the SCEVParameterRewriter only. With
this patch we will do the rewriting on demand only and also
recursively, thus not only on the top-level.

This patch teaches InstCombiner how to convert a SSSE3/AVX2 byte shuffle to a
builtin shuffle if the mask is constant.
Converting byte shuffle intrinsic calls to builtin shuffles can help finding
more opportunities for combining shuffles later on in selection dag.
We may end up with byte shuffles with constant masks as the result of inlining.

When building a plugin against an installed LLVM toolchain using
add_llvm_loadable_module (in the documented manner) doesn't work as nothing sets
the *_OUTPUT_INTDIR variables causing an error when set_output_directory is
called. Making those arguments optional (causing the default output directory
to be used) fixes this.

- Remove virtual SC_OpenCLWorkGroupLocal storage type specifier
as it conflicts with static local variables now and prevents
diagnosing static local address space variables correctly.
- Allow static local and global variables (OpenCL2.0 s6.8 and s6.5.1).
- Improve diagnostics of allowed ASes for variables in different scopes:
(i) Global or static local variables have to be in global
or constant ASes (OpenCL1.2 s6.5, OpenCL2.0 s6.5.1);
(ii) Non-kernel function variables can't be declared in local
or constant ASes (OpenCL1.1 s6.5.2 and s6.5.3).

FunctionParmPackExpr actually stores an array of ParmVarDecl* (and
accessors return that). But, the FunctionParmPackExpr::Create()
constructor accepted an array of Decl *s instead.
It was easy for this mismatch to occur without any obvious sign of
something wrong, since both the store and the access used independent
'reinterpet_cast<XX>(this+1)' calls.
