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 a reland of abb0075 with all followup changes and fixes that
should address issues that were reported in PR44780.

As of GN 3028c6a426a4, the hack that transformed "libs" ending in
".framework" from -l arguments to -framework arguments has been removed.
Instead, "frameworks" must be used, and the toolchain must provide

Failing test output sometimes contains control characters like \x1b (e.g.
if there was some -fcolor-diagnostics output) which are not allowed inside
XML files. This causes problems with CI systems: for example, the Jenkins
JUnit XML will throw an exception when ecountering those characters and
similar problems also occur with GitLab CI.

This produces a chrome://tracing compatible trace file in the same way
as -ftime-trace.
This can be useful in optimising test time where one long test is causing
long overall test time on a wide machine.
This also helped in finding tests which have side effects on others
(e.g. https://reviews.llvm.org/D84885).

"[llvm-dev] Multiple documents in one test file" for some discussions.
This patch has explored several alternatives. The current semantics are similar to
what @dblaikie proposed.
`split-file filename output` splits the input file into multiple parts separated by
regex `^(.|//)--- filename` and write each part to the file `output/filename`
(`filename` can include path separators).
Use case A (organizing input of different formats (e.g. linker
script+assembly) in one file).
```
# RUN: split-file %s %t
# RUN: llvm-mc %t/asm -o %t.o
# RUN: ld.lld -T %t/lds %t.o -o %t
This is sometimes better than the %S/Inputs/ approach because the user
can see the auxiliary files immediately and don't have to open another file.
# asm
...
# lds
...
```
Use case B (for utilities which don't have built-in input splitting
feature):
```
// RUN: split-file %s %t
// RUN: llc < %t/1.ll | FileCheck %s --check-prefix=CASE1
// RUN: llc < %t/2.ll | FileCheck %s --check-prefix=CASE2
Combing tests prudently can improve readability.
For example, when testing parsing errors if the recovery mechanism isn't possible,
grouping the tests in one file can more readily see test coverage/strategy.
//--- 1.ll
...
//--- 2.ll
...
```
Since this is a new utility, there is no git history concerns for
UpperCase variable names. I use lowerCase variable names like mlir/lld.

Not passing --clang would result in a python exception after this change:
(TypeError: expected str, bytes or os.PathLike object, not NoneType)
because the --clang argument default was only being populated in the
initial argument parsing pass but not later on.
Fix this by adding an argparse callback to set the default values.

The check-* targets run ${Python3_EXECUTABLE} $BUILD/bin/llvm-lit, but

This makes clang default to -Wa,-mrelax-relocations=yes, which enables
R_386_GOT32X (GNU as enables it regardless of -mrelax-relocations=) and
R_X86_64_[REX_]GOTPCRELX in MC. The produced object files require GNU ld>=2.26
to link. binutils 2.26 is considered a very old release today.
This reverts commit 59d6e814ce0e7b40b7cc3ab136b9af2ffab9c6f8.
The cause for the revert (3 clang tests running opt -ipconstprop) was
fixed by removing those lines.
As far as I know, ipconstprop has not been used in years and ipsccp has
been used instead. This has the potential for confusion and sometimes
leads people to spend time finding & reporting bugs as well as
updating it to work with the latest API changes.
This patch moves the tests over to SCCP. There's one functional difference
I am aware of: ipconstprop propagates for each call-site individually, so
for functions that are called with different constant arguments it can sometimes
produce better results than ipsccp (at much higher compile-time cost).But
IPSCCP can be thought to do so as well for internal functions and as mentioned
earlier, the pass seems unused in practice (and there are no plans on working
towards enabling it anytime).

Substitutions are already reported in the diagnostics appearing before
the input dump in the case of failed directives, and they're reported
in traces (produced by `-vv -dump-input=never`) in the case of
successful directives. However, those reports are not always
convenient to view while investigating the input dump, so this patch
adds the substitution report to the input dump too. For example:
```
$ cat check
CHECK: hello [[WHAT:[a-z]+]]
CHECK: [[VERB]] [[WHAT]]
$ FileCheck -vv -DVERB=goodbye check < input |& tail -8
<<<<<<
1: hello world
check:1 ^~~~~~~~~~~
2: goodbye word
check:2'0 X~~~~~~~~~~~ error: no match found
check:2'1 with "VERB" equal to "goodbye"
check:2'2 with "WHAT" equal to "world"
>>>>>>
```
Without this patch, the location reported for a substitution for a
directive match is the directive's full match range. This location is
misleading as it implies the substitution itself matches that range.
This patch changes the reported location to just the match range start
to suggest the substitution is known at the start of the match. (As
in the above example, input dumps don't mark any range for
substitutions. The location info in that case simply identifies the
right line for the annotation.)

As briefly discussed in IRC with @craig.topper,
the pass is disabled basically since it's original introduction (nov 2018)
due to known correctness issues (miscompilations),
and there hasn't been much work done to fix that.
While i won't promise that i will "fix" the pass,
i have looked at it previously, and i'm sure i won't try to fix it

The DAG behavior allows matchching input patterns with a single result
to the first result of an output instruction that defines multiple
results. The remaining defs are implicitly dead.
This starts to fix using manual selection for AMDGPU add/sub (although
it's still needed, mostly because it's also still needed for
G_PTR_ADD).
