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 is primarily motivated by the desire to move from Python2 to

the python interpreter in use. Since the LLVM build seems to be able to
completed successfully with python3, use that across the build. The old

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.)

Summary:
Clang performs various recursive operations (such as template instantiation),
and may use non-trivial amounts of stack space in each recursive step (for
instance, due to recursive AST walks). While we try to keep the stack space
used by such steps to a minimum and we have explicit limits on the number of
such steps we perform, it's impractical to guarantee that we won't blow out the
stack on deeply recursive template instantiations on complex ASTs, even with
only a moderately high instantiation depth limit.
The user experience in these cases is generally terrible: we crash with
no hint of what went wrong. Under this patch, we attempt to do better:
* Detect when the stack is nearly exhausted, and produce a warning with a
nice template instantiation backtrace, telling the user that we might
run slowly or crash.
* For cases where we're forced to trigger recursive template
instantiation in arbitrarily-deeply-nested contexts, check whether
we're nearly out of stack space and allocate a new stack (by spawning
a new thread) after producing the warning.

When plugins aren't enabled, don't try to run plugins tests. Don't
enable plugins unconditionally based on the platform, instead check
if LLVM shared library is actually being built which may not be the
case for every host configuration, even if the host itself supports

Current testing setup for analyzer tests with Z3 is rather inconvenient:
There's no way to run the analyzer tests separately (I use
LIT_FILTER=Analysis ninja check-clang, but a direct target is nicer).
When Clang is built with Z3 support, there's no way to *not* run tests
with Z3 solver, and this is often desired, as tests with Z3 solver take
a very long time.
This patch introduces two extra targets:
- check-clang-analyzer
- check-clang-analyzer-z3
which solve those problems.
