and we couldn't find a dyld binary on the debug system, override
that setting and read dyld out of memory - we need to put an
internal breakpoint on dyld to register binaries being loaded or
unloaded; the debugger won't work right without dyld symbols.

MMI must match the function passed, and MF has a handle on MMI. Use that instead
of accepting it as separate argument. No Functional Change.

Save the function in the class, and then don't pass it around. This reduces the
number of parameters and makes calls to member functions simpler.
No Functional Change.

Rename AllVRegsAllocated to NoVRegs. This avoids the connotation of
running after register and simply describes that no vregs are used in
a machine function. With that we can simply compute the property and do
not need to dump/parse it in .mir files.

This patch changes LLVM_CONSTEXPR variable declarations to const
variable declarations, since LLVM_CONSTEXPR expands to nothing if the
current compiler doesn't support constexpr. In all of the changed
cases, it looks like the code intended the variable to be const instead
of sometimes-constexpr sometimes-not.

This should be uniqued when linking, but right now it creates
a lot of metadata spam listing the same version. This should also
probably be reporting the compiled version of the user program,
which may differ from the library. Currently the library IR files report
1.0 while 1.1/1.2 are the default for user programs.

PlatformRemoteAppleWatch, PlatformRemoteAppleTV and remove the
GetFileInSDKRoot method from those classes.
The rewrite uses the more modern FileSpec etc API to simplify,
and handles the case where an SDK Root is given to lldb with
the "/Symbols" directory name already appended. The new version
will try appending "/Symbols" and "/Symbols.Internal" to the
sdk root directories, and will also try appending nothing to
the sdk root directory in case it's handed such an sdkroot.

If the inline info is not duplicated into the skeleton CU, then there's
value in using -gsplit-dwarf and -gmlt together (to keep all those extra
subprograms out of the skeleton CU, while also producing smaller .dwo
files)

There was no logic in foldICmpDivConstant, so no need for a separate function.
The code is directly copy/pasted, so further cleanups to follow.

tracksSubRegLiveness only depends on the Subtarget and a cl::opt, there
is not need to change it or save/parse it in a .mir file.
Make the field const and move the initialization LiveIntervalAnalysis to the
MachineRegisterInfo constructor. Also cleanup some code and fix some
instances which better use MachineRegisterInfo::subRegLivenessEnabled() instead
of TargetSubtargetInfo::enableSubRegLiveness().

Summary:
The point of this patch is to have a consistent convention for naming build, check and install targets so that the targets can be constructed from the project name.
This change renames a bunch of CMake components and targets from libcxx to cxx. For each renamed target I've added a convenience target that matches the old target name and depends on the new target. This will preserve function of the old targets so that the change doesn't break the world. We can evaluate if it is worth removing the extra targets later.

The oneshot probe only gets executed the first time the probe is hit in the process. For order file generation this is really all we care about.

The newer event-based tests I added neglected to do the
macOS 10.12 check in the setup. This caused earlier macOS
test suite runs to attempt to compile code that doesn't exist.

The cost of predicating a diamond is only the instructions that are not shared
between the two branches. Additionally If a predicate clobbering instruction
occurs in the shared portion of the branches (e.g. a cond move), it may still
be possible to if convert the sub-cfg. This change handles these two facts by
rescanning the non-shared portion of a diamond sub-cfg to recalculate both the
predication cost and whether both blocks are pred-clobbering.
Fixed 2 bugs before recommitting. Branch instructions must be compared and found
identical before diamond conversion. Also, predicate-clobbering instructions in
the shared prefix disqualifies a potential diamond conversion. Includes tests
for both.

per-frame stack usage enough to cause it to hit our stack limit. This is not
ideal; we should find a better way of dealing with this, such as increasing
our stack allocation when built with ASan.

A branch-distance to a Thumb function shouldn't be forced to be odd for
CBZ/CBNZ instructions because (assuming it's within range), it's going to be a
valid, even offset.

Give appropriate warnings with -Wdocumentation for @param comments
that refer to function aliases defined with 'using'. Very similar
to typedef's behavior. This does not add support for
TypeAliasTemplateDecl yet.

The return value from PlatformExecutor::allocateDeviceMemory needs to be
converted from Expected<GlobalDeviceMemoryBase> to

A similar bug is also fixed for Executor::allocateHostMemory.
