Delete CloudABI support

[brad]

Summary

After this https://reviews.llvm.org/D108637 and with FreeBSD -current and now 14 dropping support for CloudABI I think it is time to consider deleting the CloudABI support.

[MaskRay]

Thanks for the cleanup.

[brad]

Missed BUILD.gn, a unit test and one or two other files.

[brad]

Also..

# RUN: llvm-mc -filetype=obj -triple=aarch64-unknown-cloudabi %s -o %t.o
./lld/test/ELF/aarch64-got-relocations.s
// RUN: llvm-mc -filetype=obj -triple=i686-unknown-cloudabi %s -o %t.o
./lld/test/ELF/static-with-export-dynamic.s
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-cloudabi %s -o %t1.o
./lld/test/ELF/x86-64-tls-pie.s

The only run lines in these tests are CloudABI targets and that triple is going away.

[brad]

Rebase.

[brad]

Looking for any feedback from the FreeBSD guys.

Sorry for no reply earlier, I was away for some of the summer and missed this originally. While CloudABI was a very interesting FreeBSD-related project it was removed from FreeBSD as you noted, and there's no reason to keep support in llvm

    Drop cloudabi
    
    According to https://github.com/NuxiNL/cloudlibc:
    CloudABI is no longer being maintained. It was an awesome experiment,
    but it never got enough traction to be sustainable.
    
    There is no reason to keep it in FreeBSD.
