Windows doesn't properly support pass plugins (as a shared library
can't have undefined references, which pass plugins assume, being
loaded into a host process that contains provides them), thus
disable building it and the corresponding test.
This matches what was done for the passes unit test in
bc8e44218810c0db6328b9809c959ceb7d43e3f5.

The problem on Windows was that the \b in "..\bin" was interpreted
as an escape sequence. Use r"" strings to prevent that.
This reverts commit ab11b9eefa16661017c2c7b3b34c46b069f43fb7,
with raw strings in the lit.site.cfg.py.in files.
Differential Revision: https://reviews.llvm.org/D77184
Currently, all generated lit.site.cfg files contain absolute paths.
This makes it impossible to build on one machine, and then transfer the
build output to another machine for test execution. Being able to do
this is useful for several use cases:
1. When running tests on an ARM machine, it would be possible to build
on a fast x86 machine and then copy build artifacts over after building.
2. It allows running several test suites (clang, llvm, lld) on 3
different machines, reducing test time from sum(each test suite time) to
max(each test suite time).
This patch makes it possible to pass a list of variables that should be
relative in the generated lit.site.cfg.py file to
configure_lit_site_cfg(). The lit.site.cfg.py.in file needs to call
`path()` on these variables, so that the paths are converted to absolute
form at lit start time.
The testers would have to have an LLVM checkout at the same revision,
and the build dir would have to be at the same relative path as on the
builder.
This does not yet cover how to figure out which files to copy from the
builder machine to the tester machines. (One idea is to look at the
`--graphviz=test.dot` output and copy all inputs of the `check-llvm`
target.)

a2ca1c2d "build: disable zlib by default on Windows"
2181bf40 "[CMake] Link against ZLIB::ZLIB"
1079c68a "Attempt to fix ZLIB CMake logic on Windows"
This changed the output of llvm-config --system-libs, and more
importantly it broke stand-alone builds. Instead of piling on more fix
attempts, let's revert this to reduce the risk of more breakages.
And add llvm-go back to the test dependencies.
No longer necessary now that llvm-go has been brought back.
This reverts commit e8f8873da5eaad187f82dad78ebdb3ab3df22b36.
EXCLUDE_FROM_ALL means something else for add_lit_testsuite as it does
for something like add_executable. Distinguish between the two by
renaming the variable and making it an argument to add_lit_testsuite.

As discussed on the mailing list, I plan to introduce an ml-compatible MASM assembler as part of providing more of the Windows build tools. This will be similar to llvm-mc, but with different command-line parameters.
This placeholder is purely a stripped-down version of llvm-mc; we'll eventually add support for the Microsoft-style command-line flags, and back it with a MASM parser.
Relanding this revision after fixing ARM-compatibility issues.

Rather than handling zlib handling manually, use `find_package` from CMake
to find zlib properly. Use this to normalize the `LLVM_ENABLE_ZLIB`,
`HAVE_ZLIB`, `HAVE_ZLIB_H`. Furthermore, require zlib if `LLVM_ENABLE_ZLIB` is
set to `YES`, which requires the distributor to explicitly select whether
zlib is enabled or not. This simplifies the CMake handling and usage in
the rest of the tooling.
This restores 68a235d07f9e7049c7eb0c8091f37e385327ac28,

This adds an alias for llvm-symbolizer with different defaults so that
it can be used as a drop-in replacement for GNU's addr2line.
If a substring "addr2line" is found in the tool's name:
* it defaults "-i", "-f" and "-C" to OFF;
* it uses "--output-style=GNU" by default.

Follow up for D53051
This patch introduces the tool associated with the ELF implementation of
TextAPI (previously llvm-tapi, renamed for better distinction). This
tool will house a number of features related to enalysis and
manipulation of shared object's exposed interfaces. The first major
feature for this tool is support for producing binary stubs that are
useful for compile-time linking of shared objects. This patch introduces
beginnings of support for reading binary ELF objects to work towards
that goal.
Added:
- elfabi tool.
- support for reading architecture from a binary ELF file into an
ELFStub.
- Support for writing .tbe files.

Many editors and Python-related diagnostics tools such as
debuggers break or fail in mysterious ways when python files
don't end in .py. This is especially true on Windows, but
still exists on other platforms. I don't want to be too heavy
handed in changing everything across the board, but I do want
to at least *allow* lit configs to have .py extensions. This
patch makes the discovery process first look for a config file
with a .py extension, and if one is not found, then looks for
a config file using the old method. So for existing users, there
should be no functional change.
