[DAGCombiner] Add vector demanded elements support to computeKnownBits
Currently computeKnownBits returns the common known zero/one bits for all elements of vector data, when we may only be interested in one/some of the elements.
This patch adds a DemandedElts argument that allows us to specify the elements we actually care about. The original computeKnownBits implementation calls with a DemandedElts demanding all elements to match current behaviour. Scalar types set this to 1.
The approach was found to be easier than trying to add a per-element known bits solution, for a similar usefulness given the combines where computeKnownBits is typically used.
I've only added support for a few opcodes so far (the ones that have proven straightforward to test), all others will default to demanding all elements but can be updated in due course.
DemandedElts support could similarly be added to computeKnownBitsForTargetNode in a future commit.

Summary:
This patch adds semantic checking and building of the fall-through `co_return;` statement as well as the `p.set_exception(std::current_exception())` call for handling uncaught exceptions.
The fall-through statement is built and checked according to:
> [dcl.fct.def.coroutine]/4
> The unqualified-ids return_void and return_value are looked up in the scope of class P. If
> both are found, the program is ill-formed. If the unqualified-id return_void is found, flowing

> the end of a coroutine results in undefined behavior.
Similarly the `set_exception` call is only built when that unqualified-id is found in the scope of class P.
Additionally this patch adds fall-through warnings for non-void returning coroutines. Since it's surprising undefined behavior I thought it would be important to add the warning right away.

Do not assume that FP vector operands are never legalized by expanding
This patch ensures that if a floating point vector operand is legalized by
expanding, it is legalized through the stack rather than by calling
DAGTypeLegalizer::IntegerToVector which will cause a failure since the operand

In a normal lld run we can just call _exit immediately after renaming

Reapply: "Remove debug location from common tail when tail-merging"
This reapplies revision 285093. Original commit message:
The branch folding pass tail merges blocks into a common-tail. However, the
tail retains the debug information from one of the original inputs to the
merge (chosen randomly). This is a problem for sampled-based PGO, as hits
on the common-tail will be attributed to whichever block was chosen,
irrespective of which path was actually taken to the common-tail.
This patch fixes the issue by nulling the debug location for the common-tail.

[scudo] Lay the foundation for 32-bit support
Summary:
In order to support 32-bit platforms, we have to make some adjustments in
multiple locations, one of them being the Scudo chunk header. For it to fit on
64 bits (as a reminder, on x64 it's 128 bits), I had to crunch the space taken
by some of the fields. In order to keep the offset field small, the secondary
allocator was changed to accomodate aligned allocations for larger alignments,
hence making the offset constant for chunks serviced by it.
The resulting header candidate has been added, and further modifications to
allow 32-bit support will follow.
Another notable change is the addition of MaybeStartBackgroudThread() to allow
release of the memory to the OS.

[ubsan] Fix vptr.cpp test to be more resilient. NFC.
The test contains a switch statement in which two of the cases are
tail-merged, with the call to __ubsan_handle_dynamic_type_cache_miss_abort
in the common tail. When tail-merging occurs, the debug location of the
tail is randomly taken from one of the merge inputs. Luckily for the test,
the expected line number in the check is the one which is chosen by the
tail-merge. However, if the switch cases are re-ordered the test will
fail.
This patch disables tail-merge, making the test resilient to changes
in tail-merge, and unblocking review D25742. It does not change the
semantics of the test.
