Hi All,

Headlines this week:

1. SimlpeRemoteEPC landed in bb27e4564355 (with a number of follow-up
fixes). SimpleRemoteEPC supports remote JITing using SPS, and should make
it easier to write out-of-process JITs. It's immediate aim though is to
replace OrcRPCExecutorProcessControl (and OrcTargetProcess*), allowing us
to remove Orc RPC (which should happen soon) and unblock some upcoming
memory manager improvements.

2. Stephen Fan landed ELFNix TLV support in ff6069b8911. Thanks very much

3. Finally, I've also floated an alternative JIT TLV design in
https://llvm.org/PR51820 that should have much better performance than our
current implementation.
