TypeIDAllocator enables the allocation of new TypeIDs at runtime,
that are unique during the lifetime of the allocator.
NonMovableTypeIDOwner is a class used to define a new TypeID for each instance
of a class, using the instance address. This class cannot be copied or moved.

This change adds a pair of flags controlling whether llvm-symbolizer
attempts debuginfod lookups. Lookups are attempted if --debuginfod is
passed and disabled if --no-debuginfod is passed.
The default behavior is made more nuanced: debuginfod lookups are now
only attempted if an HTTP client is compiled in and at least one backing
debuginfod URL was configured via environment variable. Previously,
debuginfod lookups would always be attempted, even if there were no
chance that they could succeed.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the sixth batch of tests being updated (there are a significant
number of other tests left to be updated).
This is the last major stepping stone before being able to allocate the node via the folding set allocator. That will in turn allow more general SCEV predicate expression trees.
Fixes https://github.com/llvm/llvm-project/issues/53576.
There was an inconsistency in formatting of delete expressions.
Before:
```
delete (void*)a;
delete[](void*) a;
```
After this patch:
```
delete (void*)a;
delete[] (void*)a;

We're hitting a pathological compile-time case, profiled to be in
DagCombiner::visitTokenFactor and many inserts into a SmallPtrSet.
It looks like one of the paths around findBetterNeighborChains is not

This patch fixes the register parser for arm64 crashlogs.
Compared to x86_64 crashlogs, the arm64 crashlogs nests the general
purpose registers into a separate dictionary within `thread_state`
dictionary. It uses the dictionary key as the the register number.

This patch fixes a timeout issue on the ScriptedProcess test that was
happening on intel platforms. The timeout was due to a misreporting of
the StopInfo in the ScriptedThread that caused the ScriptedProcess to
never stop.
To solve this, this patch changes the way a ScriptedThread reports its
stop reason by making it more architecture specific. In order to do so,
this patch also refactors the ScriptedProcess & ScriptedThread
initializer methods to provide an easy access to the target architecture.

For those curious, the whole reason for tracking the predicate set seperately as opposed to just immediately registering the dependencies appears to be allowing the printing code to print a result without changing the PSE state. It's slightly questionable if this justifies the complexity, but since we can preserve it with local ugliness, I did so.
GCC complains about undefined reference in LibcTest.cpp and indeed the wrong version of the template has been explicitly instanciated.
This is necessary to get llvm-libc compile with GCC.

The 'bug49779.cpp' test has been failing recently. This is because the
runtime is sufficiently complex when using nested parallelism without
optimizations that the CUDA tools cannot statically determine the stack
size. Because of this the kernel can exceed the thread stack size and
crash. Work around this using the 'LIBOMPTARGET_STACK_SIZE' environment
variable and add an FAQ entry for this situation.

The last test was intended to be a negative test with D114272,
but a more general fold can reduce it, so that is renamed.
These are all single-block tests, so remove the unnecessary labels.
This reverts commit 77a0da926c as we've
received multiple reports of this significantly impacting performance,
in ways that don't seem to just be target specific cost models going
wrong. I would offer some reproducers, but the test changes here seem to
be full of them!
Reverting for now and hopefully we can remove the "hack" more carefully
as we go.
When we enable -fsplit-dwarf-inlining we end up with two entries
in .debug_aranges for each CU. Because it processes Skeleton CU
inline information and DWO CU.
Furthermore address calculations were incorrect because we were processing sections in Skeleton CU.

While testing scalable vectors I found that if we generate a
vector splice intrinsic and run the code through the loop unroller,
we'll crash due to an invalid cost.
This adds a basic cost based on the 2 slide instructions used by the
lowering in D119303.
We probably need to factor LMUL into this, but that's true for
arithmetic instructions too. So I've ignored for the moment.

In GNU ld, -dc only affects -r links and causes COMMON symbols to be allocated.
--no-define-common is defined to make COMMON symbols undefined for -shared.
AIUI --no-define-common is a workaround around glibc 2.1 time and not really useful.
gold confuses --define-common with -d/FORCE_COMMON_ALLOCATION and implements
--define-common with -d semantics. Its --no-define-common is incompatible with
GNU ld.
In ld.lld, b2a23cf3c0 fixed the default -r
behavior for COMMON symbols but ported the incompatible gold
--[no-]define-common. To the best of my knowledge, no project uses -dp
--[no-]define-common. So just remove these options.
-d/-dc are used by the following projects:
* grub grub-core/genmod.sh.in uses -Wl,-r,-d (https://lists.gnu.org/archive/html/grub-devel/2022-02/msg00088.html)
* FreeBSD crunchgen uses -Wl,-dc (https://reviews.freebsd.org/D34215)
A no-op implementation works for them. Only when a program inspects relocatable
output by itself and does not recognize COMMON symbols, there may be a problem.
This is an extremely unlikely case.
