Fix "Bad machine code" when building world for mips or mips64

Merge commit f5755c0849a5 from llvm git (by Jessica Clarke):

[Mips] Add glue between CopyFromReg, CopyToReg and RDHWR nodes for TLS

Fix "Bad machine code" when building world for mips or mips64

Merge commit f5755c0849a5 from llvm git (by Jessica Clarke):

[Mips] Add glue between CopyFromReg, CopyToReg and RDHWR nodes for TLS

The MIPS ABI requires the thread pointer be accessed via rdhwr $3, $r29.
This is currently represented by (CopyToReg $3, (RDHWR $29)) followed by
a (CopyFromReg $3). However, there is no glue between these, meaning
scheduling can break those apart. In particular, PR51691 is a report
where PseudoSELECT_I was moved to between the CopyToReg and CopyFromReg,
and since its expansion uses branches, it split the def and use of the
physical register between two basic blocks, resulting in the def being
eliminated and the use having no def. It also seems possible that a
similar situation could arise splitting up the CopyToReg from the RDHWR,
causing the RDHWR to use a destination register other than $3, violating
the ABI requirement.

Thus, add glue between all three nodes to ensure they aren't split up
during instruction selection. No regression test is added since any test
would be implictly relying on specific scheduling behaviour, so whilst
it might be testing that glue is preventing reordering today, changes to
scheduling behaviour could result in the test no longer being able to
catch a regression here, as the reordering might no longer happen for
other unrelated reasons.

Fixes PR51691.

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.
