Matt Macy 5de96e33d6 hwpmc: support sampling both kernel and user stacks when interrupted in kernel 
This adds the -U options to pmcstat which will attribute in-kernel samples
back to the user stack that invoked the system call. It is not the default,
because when looking at kernel profiles it is generally more desirable to
merge all instances of a given system call together.

Although heavily revised, this change is directly derived from D7350 by
Jonathan T. Looney.
