Introduce COMMON_COROUTINES_TEST directive.
Every test with this directive is run twice: one time with
language version 1.2 and kotlin.coroutines.experimental package
and the other time with language version 1.3 and kotlin.coroutines
package. Each run is a separate method: with suffixes _1_2 and _1_3
respectively.
However, since codegen of release coroutines is not supported in JS
backend, we generate only one method: with suffix _1_2.

descriptors that are used for body generation must be
obtained from the SUSPEND_FUNCTION_TO_JVM_VIEW
