This change adds the ability to create source tarballs for unreleased or untagged code by providing the `--git-ref <GIT_REF>` flag to the `llvm/utils/release/export.sh` script. This is useful for creating daily snapshot tarballs that can easily be consumed by packagers who want to build a daily snapshot.
The default behavior of `export.sh` hasn't changed.
You may also provide a `--template` argument to say how the artifacts
are supposed to be named (as suggested by @hans).
The `-help` output of `export.sh` was changed quite significantly to look like this:
```
Export the Git sources and build tarballs from them.
Usage: export.sh [-release|--release <major>.<minor>.<patch>]
[-rc|--rc <num>]
[-final|--final]
[-git-ref|--git-ref <git-ref>]
[-template|--template <template>]
Flags:
-release | --release <major>.<minor>.<patch> The version number of the release
-rc | --rc <num> The release candidate number
-final | --final When provided, this option will disable the rc flag
-git-ref | --git-ref <git-ref> (optional) Use <git-ref> to determine the release and don't export the test-suite files
-template | --template <template> (optional) Possible placeholders: $PROJECT $YYYYMMDD $GIT_REF $RELEASE $RC.
Defaults to '${PROJECT}-${RELEASE}${RC}.src.tar.xz'.
The following list shows the filenames (with <placeholders>) for the artifacts
that are being generated (given that you don't touch --template).
* llvm-<RELEASE><RC>.src.tar.xz
* clang-<RELEASE><RC>.src.tar.xz
* compiler-rt-<RELEASE><RC>.src.tar.xz
* libcxx-<RELEASE><RC>.src.tar.xz
* libcxxabi-<RELEASE><RC>.src.tar.xz
* libclc-<RELEASE><RC>.src.tar.xz
* clang-tools-extra-<RELEASE><RC>.src.tar.xz
* polly-<RELEASE><RC>.src.tar.xz
* lldb-<RELEASE><RC>.src.tar.xz
* lld-<RELEASE><RC>.src.tar.xz
* openmp-<RELEASE><RC>.src.tar.xz
* libunwind-<RELEASE><RC>.src.tar.xz
* flang-<RELEASE><RC>.src.tar.xz
Additional files being generated:
* llvm-project-<RELEASE><RC>.src.tar.xz (the complete LLVM source project)
* test-suite-<RELEASE><RC>.src.tar.xz (only when not using --git-ref)
To ease the creation of snapshot builds, we also provide these files
* llvm-release-<YYYYMMDD>.txt (contains the <RELEASE> as a text)
* llvm-rc-<YYYYMMDD>.txt (contains the rc version passed to the invocation of export.sh)
* llvm-git-revision-<YYYYMMDD>.txt (contains the current git revision sha1)
Example values for the placeholders:
* <RELEASE> -> 13.0.0
* <YYYYMMDD> -> 20210414
* <RC> -> rc4 (will be empty when using --git-ref)
In order to generate snapshots of the upstream main branch you could do this for example:
export.sh --git-ref upstream/main --template '${PROJECT}-${YYYYMMDD}.src.tar.xz'

Tablegen currently expects targets to have at least one
pressure set for every broader register category. AMDGPU's
VGPR or AGPR, for instance, seemed to work correctly without
any pset, though we have forced one for each type to avoid
the assertion in computeRegUnitSets. However, psets can not
be entirely empty. At least one set is mandatory for every
target. This patch bypasses the assertion for the classes
when GeneratePressureSet is zero while ensuring the
RegUnitSets are not empty.

Make the update_llc_test_checks script test independant of llc behavior
by using cat with static files to simulate llc output.
This allows changing llc without breaking the script test case.
The update script is executed in a temporary directory, so the
llc-generated assembly files are copied there. %T is deprecated, but it
allows copying a file with a predictable filename.

For x86 Darwin, we have a stack checking feature which re-uses some of this
machinery around stack probing on Windows. Renaming this to be more appropriate
for a generic feature.

Previously the script emitted output using plain CHECK directives. This
can result in a test passing even if there are some instructions between
CHECK directives that should have been removed. It also makes debugging
tests that have the output in a different order more difficult since
FileCheck can match with a later line and then complain about the "wrong"
directive not being found.
This will cause quite large diffs when updating existing tests, but I'm not sure we need an opt-in flag here.

[LLD] Remove global state in lld/COFF
This patch removes globals from the lldCOFF library, by moving globals
into a context class (COFFLinkingContext) and passing it around wherever
it's needed.
See https://lists.llvm.org/pipermail/llvm-dev/2021-June/151184.html for
context about removing globals from LLD.
I also haven't moved the `driver` or `config` variables yet.

PassBuilder.cpp is the slowest file to compile in LLVM.
When trying to test changes to pipelines, it takes a long time to recompile.
This doesn't actually speedup building PassBuilder.cpp itself since most
of the time is spent in other large/duplicated functions caused by
PassRegistry.def.

Follow-up to D109708: Using lib_dirs means this will work with ancient gn binaries.
Change the toolchain definitions to make lib_dirs have the right effect, and
pull out lib_switch of each of the tools while here.
This means we now do pass /LIBPATH: to link.exe, but since we invoke it directly
and not through clang-cl, this doesn't actually require D109624. And since this
is built in to GN, we don't need a config to push the flag to dependents.
This is arguably a bit more idiomatic, and it doesn't require folks to update
their GN binaries. No effective behavior change.

This updates llvm/utils/sysroot.py to include the "DIA SDK" folder in the
sysroot.
It also updates the build to look for the DIA SDK there if a sysroot is set.
This requires moving LLVM_WINSYSROOT to config-ix.cmake.
For the GN build, I chose to pass a qualified path to diaguids in libs instead
of pushing a config with a `/libpath:` flag. The former requires a GN with
https://gn-review.googlesource.com/c/gn/+/12200, the latter requires D109624.
The former is more like the cmake build, arguably a bit simpler, and it's
easier to check for the wrong GN revision and easier to update GN.

This is also a bug. The VK[1/2/4/8/16]PAIR here should be VK[1/2/4/8/16]Pair which has its
custom PrintMethod and ParserMatchClass. However we don't have any instructions using vvvv

On Linux, LLDB depends on lldb-server at runtime (on Mac, the dependency on
