Log:
MFC r356929:
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.
Differential Revision: https://reviews.llvm.org/D67787
Merge commit ff0311c4b from llvm git (by Justin Hibbits):
[PowerPC]: Add powerpcspe target triple subarch component
Summary:
This allows the use of '-target powerpcspe-unknown-linux-gnu' or
'powerpcspe-unknown-freebsd' to be used, instead of '-target
powerpc-unknown-linux-gnu -mspe'.

Merge commit ba91dffaf from llvm git (by Fangrui Song):
[Driver][PowerPC] Move powerpcspe logic from cc1 to Driver
Follow-up of D72014. It is more appropriate to use a target feature
instead of a SubTypeArch to express the difference.

commit 36eedfcb3 from llvm git (by Justin Hibbits):
[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.
Reviewed By: MaskRay
Differential Revision: https://reviews.llvm.org/D72673
These are needed to unbreak the build for powerpcspe.
