Some tests need to disable inlining of a function. It's currently done in one of a few ways (adding a function call, an empty switch, or a defer). Add support for a less fragile 'go:noinline' directive that prevents inlining. Fixes #12312 Change-Id: Ife444e13361b4a927709d81aa41e448f32eec8d4 Reviewed-on: https://go-review.googlesource.com/13911 Run-TryBot: Todd Neal <todd@tneal.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Josh Bleecher Snyder <josharian@gmail.com>
