value() has undesired exception checking semantics and calls
__throw_bad_optional_access in libc++. Moreover, the API is unavailable without
_LIBCPP_NO_EXCEPTIONS on older Mach-O platforms (see
_LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS).
This commit fixes LLVMAnalysis and its dependencies.
I've eliminated all uses of LLVM_HAVE_TF_API except a couple of them
being removed in llvm/lib/CodeGen/CMakeLists.txt. This patch removes
remaining definitions and uses of LLVM_HAVE_TF_API.

This reverts commit a888825aeef8d6592c6cf5f4e5854cc39af49633.
This changes the default output of UTC, and as such introduces
spurious changes whenever existing tests are regenerated.
I've indicated in https://reviews.llvm.org/D139006#3989954 how
this can be implemented without causing test churn.
Also add 'system-zos' as a lit feature and use it where needed.
Part of the project to eliminate special handling for triples in lit
expressions.

Previously, the label also matched function calls with the function
name, which caused tests to fail because the label matched on the wrong
line.
Add the `define` prefix, so only function defines are matched.

9ebaf4fef4aac89 removed one of two redundant deps in CMake, but it removed the
one dep in the GN build. Since the CMake build still has the dep, so should the
GN build. (Things don't link without it.)
Reland 42c2dc401742266da3e0251b6c1ca491f4779963 which was reverted
in cb03b1bd99313a728d47060b909a73e7f5991231. The fix for the link
errors was to reintroduce one of the two occurences of 'Scalar'
under the LINK_COMPONENTS.

This patch proposes to add a !listremove() bang operator to allow us to prune list entries by removing any entries from the first list arg that are also contained in the second list arg.
The particular use case I have in mind is for improved analysis of x86 scheduler models for which I'm hoping to start using the CodeGenProcModel 'Unsupported' features lists, which lists the ISA features a particular model DOESN'T support - with such a diverse and growing list of x86 ISAs, I don't want to have to update all these lists with every ISA change to every model - so I'm intending to keep a single central list of all x86 features, and then have the each model "remove" the features that it supports via a !listremove() - leaving just the unsupported ones.

As a reminder, UTC_ARGS is used by lit test cases to specify which
arguments need to be passed to update_XXXX_test_checks.py to be
auto-updated properly.
The support is achieved by relying on common.itertests, which is what
other test
updaters use to iterate over test files.
This commit also changes how the --llc-binary option is saved in args.
It used to be saved as "llc", but it is here changed to the standard
"llc_binary" to make use of an existing ignore mechanism for specific
arguments. Without that change, the option would not be ignored and
would appear in UTC_ARGS. This would be different from what e.g.
update_llc_test_checks does. As update_mir_test_checks.py now supports
UTC_ARGS, it became important to ensure the option is ignored.

Generation of CHECK lines for fixedStack can be enabled with --print-fixed-stack.
This is particularly useful for tests which need to inspect how the
stack looks, e.g. for ABI tests.
See the other stacked revision building on top of this one which enables UTC_ARGS (in a similar fashion to other test updaters in utils/).

It is generally good practice, if you know how big the vector is going to be in the end, to reserve before continually calling "push_back" or "emplace_back"

Commit a538d1f13a13 first added support for named sub-operands in
CodeEmitterGen. We now add a few more features to that, enabling
further target cleanups.
1. Adds support for handling an EncoderMethod in a sub-operand in
CodeEmitterGen. Previously, the specified encoder of a sub-operand was
ignored, and only the default used.
2. Adds support for sub-operands in DecoderEmitter, along with support
for tied sub-operands.
The changes to the decoder required a few minor tweaks to a few
targets, where existing brokeness was exposed. In order to keep this
patch small, I left FIXMEs which will be addressed in upcoming
patches. (Except MIPS16, since its object file emission/decoding is
totally broken).
