[llvm-dev] RFC Process

[David Greene via llvm-dev]

I was about to post an RFC for a memory system model for LLVM but
noticed Hal's updated to his test-suite benchmarks RFC.

What's the suggested process for introducing RFCs?  Is it best to put it
under docs/Proposals and open a Phab differential?  Or is an initial
mailing list post preferred, with further discussion leading to a
document in docs/Proposals tracked on Phab?
