When a class property is accessed with an object instance, before this commit,
we try to apply a typo correction of the same property:
property 'c' not found on object of type 'A *'; did you mean 'c'?
With this commit, we correctly emit a diagnostics:
property 'c' is a class property; did you mean to access it with class 'A'?

Summary:
This fixes bug: https://llvm.org/bugs/show_bug.cgi?id=28282
Currently the cost model of constant hoisting checks the bit width of the data type of the constants.
However, the actual immediate value is small enough and not need to be hoisted.
This patch checks for the actual bit width needed for the constant.

Summary: LLVM assumes that large clearance will hide the partial register spill penalty. But in our experiment, 16 clearance is too small. As the inserted XOR is normally fairly cheap, we should have a higher clearance threshold to aggressively insert XORs that is necessary to break partial register dependency.

Our existing yaml::Output code writes tags immediately when mapTag is called, without any state handling. This results in tags on sequence elements being written before the element itself. For example, we see this:
SomeArray: !elem_type
- key1: 1
key2: 2 !elem_type2
- key3: 3
key4: 4
We should instead see:
SomeArray:
- !elem_type
key1: 1
key2: 2
- !elem_type2
key3: 3
key4: 4
Our reader handles reading properly, so this bug only impacts writing yaml sequences with tagged elements.
As a test for this I've modified the Mach-O yaml encoding to allways apply the !mach-o tag when encoding MachOYAML::Object entries. This results in the !mach-o tag appearing as expected in dumped fat files.

Summary: SystemZ shift instructions only use the last 6 bits of the shift
amount. When the result of an AND operation is used as a shift amount, this
means that we can use the NILL instruction (which operates on the last 16 bits)
rather than NILF (which operates on the last 32 bits) for a 16-bit savings in
instruction size.

We continue accepting "macosx" but canonicalize it to "macos", When emitting
diagnostics, we use "macOS" instead of "OS X".
The PlatformName in TargetInfo is changed from "macosx" to "macos" so we can
directly compare the Platform in AvailabilityAttr with the PlatformName
in TargetInfo.

I think this converts all the simple cases that really just care about
the generated code being position independent or not. The remaining
uses are a bit more complicated and are checking things like "is this
a library or executable" or "can this symbol be preempted".

This allows command line tools to use syntaxes like the following:
llvm-foo.exe command1 -o1 -o2
llvm-foo.exe command2 -p1 -p2
Where command1 and command2 contain completely different sets of
valid options. This is backwards compatible with previous uses
of llvm cl which did not support subcommands, as any option
which specifies no optional subcommand (e.g. all existing
code) goes into a special "top level" subcommand that expects
dashed options to appear immediately after the program name.
For example, code which is subcommand unaware would generate
a command line such as the following, where no subcommand
is specified:
llvm-foo.exe -q1 -q2
The top level subcommand can co-exist with actual subcommands,
as it is implemented as an actual subcommand which is searched
if no explicit subcommand is specified. So llvm-foo.exe as
specified above could be written so as to support all three
aforementioned command lines simultaneously.
There is one additional "special" subcommand called AllSubCommands,
which can be used to inject an option into every subcommand.
This is useful to support things like help, so that commands
such as:
llvm-foo.exe --help
llvm-foo.exe command1 --help
llvm-foo.exe command2 --help
All work and display the help for the selected subcommand
without having to explicitly go and write code to handle each
one separately.
This patch is submitted without an example of anything actually
using subcommands, but a followup patch will convert the
llvm-pdbdump tool to use subcommands.

UNICODE and _UNICODE defintions were added in the LLVM CMake build system.
While on Unices, the UNICODE/_UNICODE macros don't cause problems, on Windows
only ittnotify_static.c should be compiled using -DUNICODE. We are still
looking at a proper fix, but this change sets the build back to exactly what it
was doing before. Also, a comment and TODO were added in the src/CMakeLists.txt
file to help explain.

Replace inheriting constructors implementation with new approach, voted into
C++ last year as a DR against C++11.
Instead of synthesizing a set of derived class constructors for each inherited
base class constructor, we make the constructors of the base class visible to
constructor lookup in the derived class, using the normal rules for
using-declarations.
For constructors, UsingShadowDecl now has a ConstructorUsingShadowDecl derived
class that tracks the requisite additional information. We create shadow
constructors (not found by name lookup) in the derived class to model the
actual initialization, and have a new expression node,
CXXInheritedCtorInitExpr, to model the initialization of a base class from such
a constructor. (This initialization is special because it performs real perfect
forwarding of arguments.)
In cases where argument forwarding is not possible (for inalloca calls,
variadic calls, and calls with callee parameter cleanup), the shadow inheriting
constructor is not emitted and instead we directly emit the initialization code
into the caller of the inherited constructor.
Note that this new model is not perfectly compatible with the old model in some
corner cases. In particular:
* if B inherits a private constructor from A, and C uses that constructor to
construct a B, then we previously required that A befriends B and B
befriends C, but the new rules require A to befriend C directly, and
* if a derived class has its own constructors (and so its implicit default
constructor is suppressed), it may still inherit a default constructor from
a base class

When using the LLVM_BUILD_EXTERNAL_COMPILER_RT option with
LLVM_ENABLE_TESTS we should also bind check-compiler-rt to check-all so
that the compiler-rt tests run too.

This is a resubmittion of 263158 change after fixing the existing problem with intrinsics mangling (see LTO and intrinsics mangling llvm-dev thread for details).
This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace.
The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics.
