Fix some of the bytecodeText tests

The changes are necessary because of release coroutines support:
- Get rid of suspendCoroutineOrReturn calls. It's anyway irrelevant
to what is being tested here

- In varValueConflictsWithTable.kt, variables slots have been shifted
because the variable for continuation's exception was removed

- In varValueConflictsWithTableSameSort.kt, a variable has been introduced
to preserve the same slot numbers for old variables.
Otherwise, they become shifted and to the second slot,
and there are a lot of irrelevant "ALOAD 2" instructions

This change is another example of why bytecode text tests are evil
