JIT threshold controlled by environment variable
* libguile/jit.c (scm_jit_counter_threshold): Make a static variable
instead of a compile-time constant.
(scm_init_jit): Init scm_jit_counter_threshold from
GUILE_JIT_COUNTER_THRESHOLD environment variable. Default is -1
indicating "never JIT".
* libguile/vm-engine.c (instrument-entry, instrument-loop): Adapt to new
variable.
