Suren Baghdasaryan ada57da3b1 FROMLIST: psi: introduce state_mask to represent stalled psi states 
The psi monitoring patches will need to determine the same states as
record_times().  To avoid calculating them twice, maintain a state mask
that can be consulted cheaply.  Do this in a separate patch to keep the
churn in the main feature patch at a minimum.

This adds 4-byte state_mask member into psi_group_cpu struct which results
in its first cacheline-aligned part becoming 52 bytes long.  Add explicit
values to enumeration element counters that affect psi_group_cpu struct
size.
