6ef0f0baae Fix CPU cycles counter to play nicely with setjmp.
setjmp clobbers non-volatile local variables. bb_start_la is such
a local variable that is used for counting of virtual CPU cycles.
To make cycles counting work after setjmp, the global variable
glob_bb_start_la is used to preserve content of bb_start_la accross
interpreter pipeline.
