stored relative to VFRAME
Summary:
This patch makes LLDB able to retrieve proper values for function arguments and
local variables stored in PDB relative to VFRAME register.
Patch contains retrieval of corresponding FPO table entries from PDB and a
generic translator from FPO programs to DWARF expressions to get correct VFRAME
value.
Patch also improves variables-locations.test and makes this test passable on
x86.

The test was using ASSERT_EQ instead of ASSERT_STREQ which meant we were
comparing string addresses instead of the actual string. This caused the
test to fail with with the sanitizers enabled.

Summary:
The method find_matching_slice(self) uses uuid_str on one of the paths but the variable does not exist and so this results in a NameError exception if we take that path.

One considers it integer division, the other doesn't.
Move to `//` (floor division) so that this test passes

Summary:

The current LLDB website is written in HTML which is hard to maintain.
We have quite a bit of HTML code checked in which can make it hard to
differentiate between documentation written by us and documentation
generated by a tool.
In line with the other LLVM projects, I propose generating the
documentation with Sphix. I think text/rst files provide a lower barrier
for new or casual contributors to fix or update.
This patch adds a copy of the LLDB website and documentation in
reStructuredText. It also adds a new ninja target `docs-lldb-html` when
-DLLVM_ENABLE_SPHINX:BOOL is enabled.
This is the first step in having the website and documentation being
generated from the repository, rather than having the output checked-in
under the www folder. During the hopefully short transition period,
please also update the reStructuredText files when modifying the
website.

Summary:
D57334 added entitlements support in `add_llvm_library()` so we can use it for library targets in LLDB.
Additionally this patch fixes the way that the entitlements argument is passed on from `add_lldb_executable()` to `add_llvm_executable()`. We still need the explicit parsing and passing on of single- and multi-value arguments as long as we are on CMake < 3.7 (due to bug https://gitlab.kitware.com/cmake/cmake/merge_requests/133).

This patch adds the file provider which is responsible for capturing
files used by LLDB.
When capturing a reproducer, we use a file collector that is very
similar to the one used in clang. For every file that we touch, we add
an entry with a mapping from its virtual to its real path. When we
decide to generate a reproducer we copy over the files and their
permission into to reproducer folder.
When replaying a reproducer, we load the VFS mapping and instantiate a
RedirectingFileSystem. The latter will transparently use the files
available in the reproducer.
I've tested this on two macOS machines with an artificial example.
Still, it is very likely that I missed some places where we (still) use
native file system calls. I'm hoping to flesh those out while testing
with more advanced examples. However, I will fix those things in
separate patches.

llvm.org/viewvc/

to instead point to https://github.com/llvm/llvm-project.
This is *not* a trivial substitution, because additionally, all the
checkout instructions had to be migrated to instruct users on how to
use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of
checking out various projects into various subdirectories.
I've attempted to not change any scripts here, only documentation. The
scripts will have to be addressed separately.
Additionally, I've deleted one document which appeared to be outdated

Summary:
This patch adds the basic support of methods reconstruction by native PDB
plugin. It contains only most obvious changes (it processes LF_ONEMETHOD and
LF_METHOD records), some things still remain unsolved:
- mangled names retrieving;
- support of template methods.

When running the test suite on macOS with Python 3 we noticed a
difference in behavior between Python 2 and Python 3 for
seven.get_command_output. The output contained a newline with Python 3,
but not for Python 2. This resulted in an invalid SDK path passed to the
compiler.

Refactor the get_llvm_lit_path() logic to respect LLVM_EXTERNAL_LIT,
and require the fallback to be defined explicitly
as LLVM_DEFAULT_EXTERNAL_LIT. This fixes building libcxx standalone
after r346888.
The old logic was using LLVM_EXTERNAL_LIT both as user-defined cache
variable and an optional pre-definition of default value from caller
(e.g. libcxx). It included a hack to make this work by assigning
the value back and forth but it was fragile and stopped working
in libcxx.
The new logic is simpler and more transparent. Default value is
provided in a separate variable, and used only when user-specified
variable is empty (i.e. not overriden).

Summary:
The field `m_decompression_scratch_type` is only used when `HAVE_LIBCOMPRESSION` is
defined, which caused a warning which I fixed in rLLDB350675 by just marking the variable as always used.
This patch fixes this in a better way by only defining the variable (and the related `m_decompression_scratch`
variable) when `HAVE_LIBCOMPRESSION` is defined. This also required changing the way we handle
`HAVE_LIBCOMPRESSION` works, as this was previously always defined on macOS within the source file
but not in the header. Now it's always defined from within our config header when CMake defines it or when
we are on macOS.
The field initialization was moved to the header to prevent that we have `#ifdef` within our initializer list.

when the binary loaded in memory has a section that we cannot find
in the on-disk version. I added this warning out of an overabundance
of caution originally, but I've never seen an instance of it being
hit in the past few years, and there are some changes for the shared
cache on darwin systems where a segment is added when the shared
cache is constructed so we're now hitting this warning. I've decided
to remove it altogether.

We use UUID::fromOptionalData to read UUID's from the Mach-O files, so UUID's
of all 0's are invalid UUID's.
We also get uuid's from debugserver, which need to match the file UUID's. So
we need an API that treats "000000000" as invalid as well. Added that and use it.
