[OpenMP] Avoid costly shadow map traversals whenever possible
In the OpenMC app we saw `omp target update` spending an awful lot of

There are two cases that allow us to avoid the traversal completely.
The simplest thing is that small updates cannot (reasonably) contain
an attached pointer part. The other case requires to track in the
mapping table if an entry might contain an attached pointer as part.
Given that we have a single location shadow map entries are created,
the latter is actually fairly easy as well.

DwarfExpression::addUnsignedConstant(const APInt &Value) only supports

expression representing the location of a variable. Before this change,
it was possible to call addUnsignedConstant on >64 bit values within a

This can trigger an assertion failure (e.g. PR52584, PR52333) when it

addUnsignedConstant on >64 bit values splits the constant into separate
DW_OP_pieces, which modifies DwarfExpression::OffsetInBits.
This change papers over the assertion errors by bailing on overly wide
DW_OP_LLVM_arg values. A more comprehensive fix might be to be to split
wide values into pointer-sized fragments.

[AArch64] Use Feature for A53 Erratum 835769 Fix
When this pass was originally implemented, the fix pass was enabled
using a llvm command-line flag. This works fine, except in the case of
LTO, where the flag is not passed into the linker plugin in order to
enable the function pass in the LTO backend.
Now LTO exists, the expectation now is to use target features rather
than command-line arguments to control code generation, as this ensures
that different command-line arguments in different files are correctly
represented, and target-features always get to the LTO plugin as they
are encoded into LLVM IR.
The fall-out of this change is that the fix pass has to always be added
to the backend pass pipeline, so now it makes no changes if the function
does not have the right target feature to enable it. This should make a
minimal difference to compile time.
One advantage is it's now much easier to enable when compiling for a
Cortex-A53, as CPUs imply their own individual sets of target-features,
in a more fine-grained way. I haven't done this yet, but it is an
option, if the fix should be enabled in more places.
Existing tests of the user interface are unaffected, the changes are to
reflect that the argument is now turned into a target feature.

[Passes] Only run extra vector passes if loops have been vectorized.
This patch uses a similar trick as in D113947 to only run the extra
passes after vectorization on functions where loops have been
vectorized.
The reason for running the 'extra vector passes' is
simplification/unswitching of the runtime checks created by LV, there
should be no need to run them if nothing got vectorized
To do that, a new dummy analysis ShouldRunExtraVectorPasses has been
added. If loops have been vectorized for a function, LV will cache the
analysis. At the moment it uses MadeCFGChanges as proxy for loop
vectorized, which isn't perfect (it could be too aggressive, e.g.
because no runtime checks have been added), but should be good enough
for now.
The extra passes are now managed by a new FunctionPassManager that
runs its passes only if ShouldRunExtraVectorPasses has been cached.

Reapply CycleInfo: Introduce cycles as a generalization of loops
Reverts
02940d6d2202. Fixes breakage in the modules build.
LLVM loops cannot represent irreducible structures in the CFG. This
change introduce the concept of cycles as a generalization of loops,
along with a CycleInfo analysis that discovers a nested
hierarchy of such cycles. This is based on Havlak (1997), Nesting of
Reducible and Irreducible Loops.
The cycle analysis is implemented as a generic template and then
instatiated for LLVM IR and Machine IR. The template relies on a new
GenericSSAContext template which must be specialized when used for
each IR.

This patch extends the `FIRToLLVMLowering` pass in Flang by adding a

instructions.
The following cases are currently supported:
1. the input object is a `!fir.complex` (wrapped in e.g. `!fir.ref` or
`!fir.box`)
2. the input object is wrapped in a `!fir.box` (including e.g.
`!fir.array`).
Note that `!fir.complex` inside a `!fir.box` falls under case 1. above
(i.e. it's a special case regardless of the wrapping type).
This is part of the upstreaming effort from the `!fir-dev` branch in [1].

Set a default number of address bits on Darwin arm64 systems
With arm64e ARMv8.3 pointer authentication, lldb needs to know how
many bits are used for addressing and how many are used for pointer
auth signing. This should be determined dynamically from the inferior
system / corefile, but there are some workflows where it still isn't
recorded and we fall back on a default value that is correct on some
Darwin environments.
This patch also explicitly sets the vendor of mach-o binaries to
Apple, so we select an Apple ABI instead of a random other ABI.
It adds a function pointer formatter for systems where pointer
authentication is in use, and we can strip the ptrauth bits off
of the function pointer address and get a different value that
points to an actual symbol.
