Arseny Kapoulkine f765d16bd9 Add external interface for creating a pass token ... Currently it's impossible for external code to register a pass because the only source file that can create pass tokens is optimizer.cpp. This makes it hard to add passes that can't be upstreamed since you can't run them from the usual pass sequence without reimplementing Optimizer. This change adds a PassToken constructor that takes unique_ptr to opt::Pass; if out-of-tree code implements opt::Pass it can register a custom pass without having to add it to SPIRV-Tools source code.		2018-05-25 09:19:43 -04:00
