  [Coroutines] Don't run optimizations for optnone functions

Currently we will run two optimization (rematerialization and sink
lifetime markers) unconditionally even if the coroutine is marked as
optnone (O0). This looks not good. This patch disables these 2
optimizations for optnone functions. An internal change shows the change
improve the compilation time for 3% in the debug build.
