Make sure the selected platform is always used
Make sure that the host uses the connect://hostname to connect to both
the lldb-platform and the lldb-gdbserver rather than what the platform
reports as the hostname of the lldb-gdbserver
Make sure that lldb-platform uses the IP address on it's connection
back to the host instead of the hostname that the host sends to it
when launching lldb-gdbserver with the remote host information
Tested on OSX and Linux

Thumbv4t does not have lo->lo copies other than MOVS,
and that can't be predicated. So emit MOVS when needed
and bail if there's a predicate.

This attribute implies indicates that the function musttail calls
another function and returns whatever it returns. The return type of the
thunk is meaningless, as the thunk can dynamically call different
functions with different return types. So long as the callers bitcast
the thunk with the correct type, behavior is well defined.
This attribute was necessary to fix PR20944, where the indirect call
combiner noticed that the thunk returned void and replaced the results
of the indirect call instruction with undef.

I believe the original code is valid, but on Windows it failed with an
assertion error saying "Expression: vector iterator is not decrementable."
Don't use rbegin and rend to workaround that error.

Since REG_ENHANCED is available on MacOSX, this allow the use of \d (digits) \b (word boundaries) and much more without affecting other systems.

yaml2obj command ran by this test took more than 15 seconds to finish
because of extremely large .bss section. Other tests only takes 3 seconds.
Reduce the size to make it faster.

This cleans up code and is more in line with the general philosophy of
modifying LiveIntervals through LiveIntervalAnalysis instead of changing
them directly.
This also fixes a case where SplitEditor::removeBackCopies() would miss
the subregister ranges.

This reverts commit r226679. For some reason it was
not generating the same behavior as manually specifying
the include dir, library path, and exe path, and it was
causing the test suite to fail to run.

This fixes it for SI. It also removes the pattern
used previously for Evergreen for f32. I'm not sure
if the the new R600 output is better or not, but it uses
1 fewer instructions if BFI is available.

CMake FindPythonLibs will look for multiple versions of Python
including both debug and release, and build up a list such as
(debug <debugpath> optimized <optimizedpath>). This confuses
the logic we have in CMake to copy the correct python dll to
the output directory so that it need not be in your system's PATH.
To alleviate this, we manually split this list and extract out
the debug and release versions of the python library, and copy
only the correct one to the output directory.

Now that we can fully specify extload legality, we can declare them
legal for the PMOVSX/PMOVZX instructions. This for instance enables
a DAGCombine to fire on code such as
(and (<zextload-equivalent> ...), <redundant mask>)
to turn it into:
(zextload ...)
as seen in the testcase changes.
There is one regression, in widen_load-2.ll: we're no longer able
to do store-to-load forwarding with illegal extload memory types.
This will be addressed separately.

Fixes 2 issues in origins arising from realloc() calls:
* In the in-place grow case origin for the new memory is not set at all.
* In the copy-realloc case __msan_memcpy is used, which unwinds stack from
inside the MSan runtime. This does not generally work (as we may be built
w/o frame pointers), and produces "bad" stack trace anyway, with several
uninteresting (internal) frames on top.
This change also makes realloc() honor "zeroise" and "poison_in_malloc" flags.

The improved completion in call context now works with:
- Functions.
- Member functions.
- Constructors.
- New expressions.
- Function call expressions.
- Template variants of the previous.
There are still rough edges to be fixed:
- Provide support for optional parameters. (fix known)
- Provide support for member initializers. (fix known)
- Provide support for variadic template functions. (fix unknown)
- Others?

AAPCS64 says that it's up to the platform to specify whether x18 is
reserved, and a first step on that way is to add a flag controlling
it.

Even sleep(1) lead to episodical flakes on some machines.
Use an invisible by tsan barrier to enforce required execution order instead.
This makes the tests deterministic and faster.
