...
The result of __builtin_clz is undefined when the source operand
is zero. Add a check for this case and handle it accordingly.

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.
