add_llvm_library and add_llvm_executable may need to create new targets with
appropriate dependencies. As a result, it is not sufficient in some
configurations (namely LLVM_BUILD_LLVM_DYLIB=on) to only call
add_dependencies(). Instead, the explicit TableGen dependencies must
be passed to add_llvm_library() or add_llvm_executable() using the DEPENDS
keyword.

deduction guides.
Previously if an implicit deduction guide had a default argument with a
cleanup, we'd leave the 'pending cleanup' flag set after declaring the
implicit guide. But it turns out that there's no reason to even
substitute into the default argument when declaring an implicit
deduction guide: we only need to record that the default argument
exists, not what it is, since we never actually form a call to a
deduction guide.
This reverts commit 737394c490.
The fp-model test was failing on platforms that enable denormal flushing
based on -ffast-math. This needs to reset to IEEE, not the default in
these cases.

llvm::call_once(initDwarfLine, [this]() { initializeDwarf(); });
Though it is not used in all places.
I need that patch for implementing "Remove obsolete debug info" feature
(D74169). But this caching mechanism is useful by itself, and I think it
would be good to use it without connection to "Remove obsolete debug info"
feature. So this patch changes inplace creation of DWARFContext with
its cached version.

There was a noop bitconvert in the load pattern. While there
also make all the sources refer to src_v.RC even though its the
same as _.RC, but its consistent.
In cmake, it is redundant to have a target list under target_link_libraries()
and add_dependency(). This patch removes the redundant dependency from
add_dependency().

Summary:
Dollar signed prefixed integers were not allowed by the AsmParser to be
used as Identifiers, differing from the GNU assembler behavior.
This patch updates the parsing of Identifiers to consider such cases as
valid, where the identifier string includes the $ prefix itself. As the
Lexer currently splits these occurrences into separate tokens, those
need to be combined by the AsmParser itself.

Summary:
ARMAsmParser was incorrectly dropping a leading dollar sign character
from symbol names in targets of branch instructions. This was caused by
an incorrect assumption that the contents following the dollar sign
token should be handled as a constant immediate, similarly to the #
token.
This patch avoids the operand parsing from consuming the dollar sign
token when it is followed by an identifier, making sure it is properly
parsed as part of the expression.

Summary:
The messages for two of the warnings are misleading:
* warn_for_range_const_reference_copy suggests that the initialization
of the loop variable results in a copy. But that's not always true,
we just know that some conversion happens, potentially invoking a
constructor or conversion operator. The constructor might copy, as in
the example that lead to this message [1], but it might also not.
However, the constructed object is bound to a reference, which is
potentially misleading, so we rewrite the message to emphasize that.
We also make sure that we print the reference type into the warning
message to clarify that this warning only appears when operator*
returns a reference.
* warn_for_range_variable_always_copy suggests that a reference type
loop variable initialized from a temporary "is always a copy". But
we don't know this, the range might just return temporary objects
which aren't copies of anything. (Assuming RVO a copy constructor
might never have been called.)
The message for warn_for_range_copy is a bit repetitive: the type of a
VarDecl and its initialization Expr are the same up to cv-qualifiers,
because Sema will insert implicit casts or constructor calls to make
them match.

Summary:
Clangd's approach is to provide lots of completions, and let ranking sort them
out. This relies on various important signals (Quality.h), without which the
large completion lists are extremely spammy.
Even with a completion result exactly at the cursor, vscode looks backwards and
tries to match the presumed partial-identifier against filterText, and uses
the result to rank, with sortText only used as a tiebreak.
By prepending the partial-identifier to the filterText, we can force the match
to be perfect and so give sortText full control of the ranking.
Full sad story: https://github.com/microsoft/language-server-protocol/issues/898
It's possible to do this on the server side too of course, and switch it on
with an initialization option. But it's a little easier in the extension, it
will get the fix to users of old clangd versions, and other editors

With AssertingVHs instead of bare pointers in
BlockFrequencyInfoImpl::Nodes (but without CallbackVHs) ~1/36 of all
tests ran by make check fail. It means that there are users of BFI that
delete basic blocks while keeping BFI. Some of those transformations add
new basic blocks, so if a new basic block happens to be allocated at
address where an already deleted block was and we don't explicitly set
block frequency for that new block, BFI will report some non-default
frequency for the block even though frequency for the block was never
set. Inliner is an example of a transformation that adds and removes BBs
while querying and updating BFI.
With this patch, thanks to updates via CallbackVH, BFI won't keep stale
pointers in its Nodes map.

The static Disassembler can be thought of as shorthands for three
operations:
- fetch an appropriate disassembler instance (FindPluginForTarget)
- ask it to dissassemble some bytes (ParseInstructions)
- ask it to dump the disassembled instructions (PrintInstructions)
The only thing that's standing in the way of this interpretation is that
the Disassemble function also does some address resolution before
calling ParseInstructions. This patch moves this functionality into
ParseInstructions so that it is available to users who call
ParseInstructions directly.
We have a test which checks that instruction-step really steps one
instruction, but the way it checks this makes it very susceptible to
codegen changes. This rewrites the test inferior to use inline assembly,
which guarantees a known sequence of instructions that the test can
check. This does mean we have to write separate assembly for each
architecture, but that is no better than having architecture-specific
assertions, which the test was already starting to accumulate.
This patch makes sure that LLDB AArch64/Linux testsuite skips
single_step_only_steps_one_instruction* tests. There is no possible
gaurantee for this test to pass and there already exists a bug report
against this bug.
