CpuProfiler: fix for GetDeoptReason code.

CpuProfiler: fix for GetDeoptReason code.

The original code always returned the first entry from RelocInfo that matched with
bailout_id. But we may have a few different deopt reasons for one bailout_id.
So we need to get the one which matches with a particular call from JumpTable.

We can do this by checking not 'target_address' (it maps to bailout_id)
but 'from' address which maps to a particular JumpTable entry.

The test was reworked so it tests identical functions against different reasons.

Can we remove the bailout_id parameter here and in its callers?
