[trace_processor] Improved sched_wakeup attribution 1. Created a spurious_sched_wakeup table Schema: - ts - thread_state_id - irq_context - utid - waker_utid This table will strictly hold wakeup information missing from the thread_state table, i.e. wakeups that occurred while a thread was already running 2. Added an irq_context column to the thread_state table to tell if a wakeup occurred in interrupt vs process context. 3. Added the raw common_flags into the raw table. This is the ftrace flag that is used to derive the irq_context value. Change-Id: I42c8f84d09c4b4853d8df86831efcf746b3475a0 Test: tools/diff_test_trace_processor.py out/android/trace_processor_shell
