[rs4gc] Fix a latent bug around attribute stripping for intrinsics
This change fixes a latent bug which was exposed by a change currently in review (https://reviews.llvm.org/D99802#2685032).
The story on this is a bit involved. Without this change, what ended up happening with the pending review was that we'd strip attributes off intrinsics, and then selectiondag would fail to lower the intrinsic. Why? Because the lowering of the intrinsic relies on the presence of the readonly attribute. We don't have a matcher to select the case where there's a glue node needed.
Now, on the surface, this still seems like a codegen bug. However, here it gets fun. I was unable to reproduce this with a standalone test at all, and was pretty much struck until skatkov provided the critical detail. This reproduces only when RS4GC and codegen are run in the same process and context. Why? Because it turns out we can't roundtrip the stripped attribute through serialized IR!
We'll happily print out the missing attribute, but when we parse it back, the auto-upgrade logic has a side effect of blindly overwriting attributes on intrinsics with those specified in Intrinsics.td. This makes it impossible to exercise SelectionDAG from a standalone test case.
At this point, I decided to treat this an RS4GC bug as a) we don't need to strip in this case, and b) I could write a test which shows the correct behavior to ensure this doesn't break again in the future.
As an aside, I'd originally set out to handle libfuncs too - since in theory they might have the same issues - but backed away quickly when I realized how the semantics of builtin, nobuiltin, and no-builtin-x all interacted. I'm utterly convinced that no part of the optimizer handles that correctly, and decided not to open that can of worms here.

[libcxx] Base MSVC autolinking on _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS
Previously the decision of which library to try to autolink was
based on _DLL, however the _DLL define (which is set by the compiler)
is tied to whether using a dynamically linked CRT or not, and the choice
of dynamic or static CRT is entirely orthogonal to whether libc++ is
linked dynamically or statically.
If _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS isn't defined, then all
declarations are decorated with dllimport, and there's no doubt that
the DLL version of the library is what must be linked.
_LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS is defined if building with
LIBCXX_ENABLE_SHARED disabled, and thus the static library is what
should be linked.
If defining _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS manually but wanting
to link against the DLL version of the library, that's not a canonical
configuration, and then it's probably reasonable to manually define
_LIBCPP_NO_AUTO_LINK too, and manually link against the desired
library.

[AArch64][GlobalISel] Implement custom legalization for s32 and s64 G_CTPOP
This is a partial port of AArch64TargetLowering::LowerCTPOP.
This custom lowering tries to uses NEON instructions to give a more efficient
CTPOP lowering when possible.
In the non-NEON/noimplicitfloat case, this should use the generic lowering
(see: https://godbolt.org/z/GcaPvWe4x). I think that's worth implementing after
implementing the widening code for s16/s8 though.

[TargetLowering] move "o" and "X" constraint handling to base class
These constraints are machine agnostic; there's no reason to handle
these per-arch. If arches don't support these constraints, then they
will fail elsewhere during instruction selection. We don't need virtual
calls to look these up; TargetLowering::getInlineAsmMemConstraint should
only be overridden by architectures with additional unique memory
constraints.

[AArch64][GlobalISel] Regbankselect + select @llvm.aarch64.neon.uaddlv
It turns out we actually import a bunch of selection code for intrinsics. The
imported code checks that the register banks on the G_INTRINSIC instruction
are correct. If so, it goes ahead and selects it.
This adds code to AArch64RegisterBankInfo to allow us to correctly determine
register banks on intrinsics which have known register bank constraints.
For now, this only handles @llvm.aarch64.neon.uaddlv. This is necessary for
porting AArch64TargetLowering::LowerCTPOP.
Also add a utility for getting the intrinsic ID from a G_INTRINSIC instruction.
This seems a little nicer than having to know about how intrinsic instructions
are structured.
