Nick Ripley 705f9848ef internal/trace: reduce event size by packing goroutine statuses
The trace parser was using an otherwise-unused event argument to hold an
extra goroutine state argument for the GoStatus & GoStatusStack events.
This is needed because the execution tracer just records the "after" for
state transitions, but we want to have both the "before" and "after"
states available in the StateTransition info for the parsed event. When
GoStatusStack was added, the size of the argument array was increased to
still have room for the extra status. However, statuses are currently
only 1 byte, and the status argument is 8 bytes, so there is plenty of
room to pack the "before" and "after" statuses in a single argument. Do
that instead to avoid the need for an extra argument.
