commit 7a8e10be0ddb8909ce25a264d03b24cee4df60cc (HEAD -> master,
origin/master, origin/HEAD)
Author: Cherry Zhang <...>
Date: Wed Jul 3 15:55:19 2019 -0400
compiler: optimize 0,1,2-case select statement
For a select statement with zero-, one-, or two-case with a
default case, we can generate simpler code instead of calling the
generic selectgo. A zero-case select is just blocking the
execution. A one-case select is mostly just executing the case. A
two-case select with a default case is a non-blocking send or
receive. We add these special cases for lowering a select
statement.

I retry to pull gollvm from https://go.googlesource.com/gollvm but it tells
me I'm already up to date.
Thanks.
