Merge commit bc4bc5aa0 from llvm git (by Justin Hibbits):

Add 8548 CPU definition and attributes

8548 CPU is GCC's name for the e500v2, so accept this in clang. The
e500v2 doesn't support lwsync, so define __NO_LWSYNC__ for this as
well, as GCC does.

[PowerPC] Fix powerpcspe subtarget enablement in llvm backend

Summary:

As currently written, -target powerpcspe will enable SPE regardless
of disabling the feature later on in the command line. Instead,
change this to just set a default CPU to 'e500' instead of a generic
CPU.

As part of this, add FeatureSPE to the e500 definition.

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.
