This is a set of tests that were all marked as failing becuse of several different bugs. A couple of the bugs are now resolved as fixed since all the tests that were failing associated with the bug are now passing. It is possible that some of them are false positives, but there's a large number of unexpectedly passing tests on Windows, so I am doing a bulk un-xfail to get the buildbot to green.

We had a use after free where we were assigning the result of a function
that returned a string to a StringRef. After fixing this use after
free, one of the DIA PDB tests now passes with the native PDB reader,
so we enable the test under native mode as well. The goal is to
eventually make all the tests pass under both, at which point we can
disable them all under DIA mode.

Prior to this change we would show the name of the section that a memory region belonged to but not its actual region name. Now we show this,. Added a test that reuses the regions-linux-map.dmp minidump file to test this and verify the correct region names for various memory regions.

The build.py script always runs the compiler in C++ mode, regardless of
the file extension. This results in mangled names presented to the
linker which in turn cannot find the printf symbol.
While we figure out how to solve this issue I've turned the source file
into a cpp file and added extern c. This should unbreak the bots.

Currently spawnLldbMi accepts both lldb-mi options and executable to debug as
a single parameter. Split them.
As in D55859 we will need to execute one lldb-mi command before loading the
exe. Therefore we can no longer use the exe as lldb-mi command-line parameter
as then there is no way to execute a command before loading exe specified as
lldb-mi command-line parameter.
LocateExecutableSymbolFileDsym should be static, that is also a little
refactorization.

We're linking against libcompression all the time now, we don't need to
fall back to zlib. zlib support will still be used when lldb is built on
linux et al systems, so I'm not removing any of the source support, but
when built on darwin with xcode, we'll be using libcompression.

We reconstruct the AST hierarchy by trying to hack up a mangled
name for the parent type using the child type's mangled name.
This was failing for enums because their tag type is represented
with two letters ("W4") instead of one letter ("T", "U", etc) as
it is with classes, structs, and unions. After accounting for
this we can now correctly determine when an enum is nested
inside of a namespace or a class.

Allocate a scratch buffer for libcompression to use when decoding

Create a scratch buffer via compression_encode_scratch_buffer_size()

As discussed on IRC this morning, when building an in-tree clang for
testing we have to have libcxx and libcxxabi checked out. This is a
common pitfall. Not only are the resulting failures non-obvious, they
only manifest when running the test suite, *after* building lldb and
clang. By making them a hard dependency (on macOS) we fail earlier with
a more useful error message.

Summary:
GnuWin32 installs libxml2 2.4. This isn't recent enough for lldb's
usage and thus the build fails. Searching for libxml2 was disabled
due to this build failure.
However, the gdb-remote plugin requires libxml2 to parse various
gdb-remote protocol packets. Thus check and confirm that the libxml2
version is at least 2.8 and disable it if not.

Summary:
The first section header does not define a real section. Instead it is
used for various elf extensions. This patch skips creation of a section
for index 0.
This has one furtunate side-effect, in that it allows us to use the section
header index as the Section ID (where 0 is also invalid). This way, we
can get rid of a lot of spurious +1s in the ObjectFileELF code.

the "self.assertEqual(thread.GetStopReason(), lldb.eStopReasonSignal)"
was occasionally failing because the stop reason would come out as
"trace" this happened if we issued the interrupt just as the processed
stopped due to single-stepping over the breakpoint (i.e., the it was not
necessary to send any signal).
Fix this by removing the breakpoint before resuming the process. This
ensures the process can run unobstructed.
After this, the test passed 200 consecutive runs successfully for me,
even while the system was under heavy load.

This test was disabled in r326756 as a part of "upstreaming debugserver

This test is passing now on linux. The same test is claimed to be flaky
on darwin, so it's possible that's true on linux too. If that's the case
we'll have to skip it here too (or fix it).
I mark the test as not-debug-info-dependent as a drive-by.

Each process plug-in can create its own custom commands. I figured it would be nice to be able to dump things from the minidump file from the lldb command line, so I added the start of the some custom commands.
Currently you can dump:
minidump stream directory
all linux specifc streams, most of which are strings
each linux stream individually if desired, or all with --linux
The idea is we can expand the command set to dump more things, search for data in the core file, and much more. This patch gets us started.

Previously the code that parsed debug info to create lldb's Symbol
objects such as Variable, Type, Function, etc was tightly coupled
to the AST reconstruction code. This made it difficult / impossible
to implement functions such as ParseDeclsForContext() that were only
supposed to be operating on clang AST's. By splitting these apart,
the logic becomes much cleaner and we have a clear separation of
responsibilities.

The --repl option was incorrectly defined as "Separate" (option and
value separated by a space). This resulted in the option not being
picked up when no value was specified.
This patch fixes the driver so that `--repl` is recognized again. I
split the option into two:
- A flag: `--repl` and `-r` which take no arguments.
- A joined option: `--repl=<flags>` and `-r=<flags>` that forward its
values to the repl.
This should match the driver's old behavior.
