AMDGPU: Don't clobber source register for V_SET_INACTIVE_*
The WWM register has unmodeled register liveness, For v_set_inactive_*,
clobberring source register is dangerous because it will overwrite the
inactive lanes. When the source vgpr is dead at v_set_inactive_lane,
the inactive lanes may be not really dead. This may make common
optimizations doing wrong.
For example in a simple if-then cfg in Machine IR:
bb.if:
%src =
bb.then:
%src1 = COPY %src
%dst = V_SET_INACTIVE %src1(tied-def 0), %inactive
bb.end
... = PHI [0, %bb.then] [%src, %bb.if]
The register coalescer will think it is safe to optimize "%src1 = COPY %src"
in bb.then. And at the same time, there is no interference for the PHI in
bb.end. The source and destination values of the PHI will be assigned
the same register. The single PHI register will be overwritten by the
v_set_inactive, then we would get wrong value in bb.end.
With this change, we will copy the content of the source register before
setting inactive lanes after register allocation. Yes, this will sacrifice
the WWM code generation a little, but I don't have any better idea to do things
correctly.

Adds libunwind support for SPARCv9 (aka sparc64). This is a rebase of @kettenis' patch D32450, which I created (with his permission) because the original review has become inactive.
The changes are of a cosmetic nature to make it fit better with the new code style, and to reuse the existing SPARCv8 code, whenever possible.
Please let me know if I posted this on the wrong place. Also, the summary of the original review is reproduced below:
> This adds unwinder support for 64-bit SPARC (aka SPARCv9). The implementation was done on OpenBSD/sparc64, so it takes StackGhost into account:
>
> https://www.usenix.org/legacy/publications/library/proceedings/sec01/full_papers/frantzen/frantzen_html/index.html
>
> Since StackGhost xor's return addresses with a random cookie before storing them on the stack, the unwinder has to do some extra work to recover those. This is done by introducing a new kRegisterInCFADecrypt "location" type that is used to implement the DW_CFA_GNU_window_save opcode. That implementation is SPARC-specific, but should work for 32-bit SPARC as well. DW_CFA_GNU_window_save is only ever generated on SPARC as far as I know.

[ELF] Avoid wrapping unreferenced lazy symbols
There's a couple of motivations here:
* LLD 12 (which I was originally testing with) was adding an undefined
symbol to the symbol table if you attempted to wrap an unreferenced
lazy symbol, which would later break `--no-allow-shlib-undefined`. LLD
on main actually produces a weak undefined symbol, so this doesn't
break anyway, but it's cleaner to not have the weak undefined symbol
as well. The new behavior also matches bfd and gold.
* PROVIDE in a linker script referencing a wrapped symbol would think
that an otherwise-unreferenced lazy symbol which was wrapped was
actually referenced, and therefore proceed with the definition, which
goes against expectations. The new behavior also matches bfd and gold.

[flang] Debugging of ACCESS='STREAM' I/O (take 2)
Corrects the runtime implementation of I/O on files with
the access mode ACCESS='STREAM'. This is a collection
of edge-case tweaks to ensure that the distinctions between
stream and direct/sequential files, unformatted or formatted,
are respected where appropriate.
Moves NextInField() from io-stmt.h to io-stmt.cpp --
it was getting too big to keep in a header.
This patch exposed a problem with the I/O runtime
on Windows and it was reverted. This version also
fixes that problem; files are now opened on Windows
in binary mode to prevent inadvertent insertions of
carriage returns before line feeds, and those line
endings (CR+LF) are now explicitly generated.

[RISCV] Remove exclusions for zext.h/zext.w from our (and (srl X, C1), C2) selection code.
This code tries to replace the pattern with a pair of shifts, but
we were excluding if the And could be a zext.h or zext.w. The SLLI/SRL
pair is more compressible and doesn't come with much down side.

Reland [SimplifyCFG] `markAliveBlocks()`: recognize that normal dest of `invoke`d `noreturn` function is `unreachable`
As per LangRef's definition of `noreturn` attribute:
```
noreturn
This function attribute indicates that the function never returns
normally, hence through a return instruction.
This produces undefined behavior at runtime if the function
ever does dynamically return. nnotated functions may still
raise an exception, i.a., nounwind is not implied.
```
So if we `invoke` a `noreturn` function, and the normal destination
of an invoke is not an `unreachable`, point it at the new `unreachable`
block.
The change/fix from the original commit is that we now actually create
the new block, and don't just repurpose the original block,
because said normal destination block could have other users.

[libc++][Docker] Don't actually start using a newer compiler in the CI
To ensure a smooth transition without breaking CI, we should use explicitly
versioned Clangs in the CI jobs definition instead, since that's a change
we can actually test in the CI.
So instead of bumping the compiler version from the Docker image, use
the same version as before by default, and we can bump it from the CI
job definition once all the nodes are running the new image.
