Only count VM instructions in YJIT stats builds

Browse source 
The instruction counter is slowing multi-Ractor applications.  I had
changed it to use a thread local, but using a thread local is slowing
single threaded applications.  This commit only enables the instruction
counter in YJIT stats builds until we can figure out a way to gather the
information with lower overhead.
