[PATCH] D68559: [RISCV] Support fast calling convention

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

I like this change.

`fastcc` is LLVM-internal only, right? Checking that we don't have to care about splitting operands that don't fit into registers, or any other psABI details, right?

You said you had some performance numbers, it would be useful to have them in a comment on this patch.
