Summary:
Added co_return statement emission.

Tweaked coro-alloc.cpp test to use co_return to trigger coroutine processing instead of co_await, since this change starts emitting the body of the coroutine and await expression handling has not been upstreamed yet.

This adds AArch64 support to recently added part of the runtime responsible for offloading to target. This piece of code allows offloading-to-self on AArch64 machines.

Summary: This patch refactors the DWARFYAML code for dumping compile units to use a visitor pattern. Using this design will, in the future, enable the DWARF YAML code to perform analysis and mutations of the DWARF DIEs. An example of such mutations would be calculating the length of a compile unit and updating the CU's Length field before writing the DIE. This support will make it easier to craft or modify DWARF tests by hand.

NewGVN: We were not really failing this testcase, because the instructions it was looking for are unused. GVN value numbers unused instructions, NewGVN does not.  Fix the instructions to be used, so we eliminate the redundancies it's checking for, and un-XFAIL it

David Blaikie pointed out that the `setForceChildren` API is no longer needed and should be removed from the DWARF Generator APIs.

Also the DWARFDebugInfoTest file had some copy pasted comments that are not relevant. I've removed them.

If a block has non-analyzable branches, the listed successors don't need
to add up to one. For example, if a block has a conditional tail call,
that tail call will not have a corresponding successor in the successor
list, but will still be a possible branch.

it was accessing the details of the Log class directly. Let it go
through the channel class instead.

This also discovered a bug when we were setting but not clearing the log
options when enabling a channel.

Before, we were producing G_INSERT instructions that were actually closer to a
cast or even a COPY when both input and output sizes are the same. This doesn't
really make sense and means that everything interpreting a G_INSERT also has to
handle all these kinds of casts.

So now we detect these degenerate cases and emit real casts instead.

This puts us at parity with bfd, which could already gc this case.

I noticed the sections not being gced when linking a modified freebsd
kernel. A section that was not gced and not mentioned in the linker
script would end up breaking the expected layout. Since fixing the gc
is relatively simple and an improvement, that seems better than trying
to hack the orphan placement code.

There are 173 input section in the entire link whose names are valid C
identifiers, so this is probably not too performance critical.

Use the store size of the argument type, which will be a byte-sized
quantity, rather than dividing the size in bits by 8.

Fixes PR32136 and re-enables copy elision from i64 arguments.

Now that G_INSERT instructions can only insert one register, this code was
overly general. In another direction it didn't handle registers that crossed
split boundaries properly, which needed to be fixed.

Summary: We do not need that special handling because the debug info is more accurate now. Performance testing shows no regression on google internal benchmarks.
