88ce9ce40c runtime: two proc bug fixes 
1. Fix bug in GOMAXPROCS when trying to cut number of procs

manifesting only on Xen hosted Linux.

add89dd1ba stack overflow debugging and fix. 
* in 6l, -K already meant check for stack underflow.
    add -KK to mean double-check stack overflows
    even in nosplit functions.

  * comment out print locks; they deadlock too easily
     but are still useful to put back for special occasions.

  * let runcgo assembly switch to scheduler stack
    without involving scheduler directly.  because runcgo
    gets called from matchmg, it is too hard to keep it
    from being called on other stacks.
