Turn on automatic JIT compilation by default

Browse source 
* libguile/jit.c (default_jit_threshold): New static const variable.
(scm_sys_jit_compile): Remove.
(scm_init_jit): Rename GUILE_JIT_COUNTER_THRESHOLD to
GUILE_JIT_THRESHOLD, and default to default_jit_threshold.  Remove
%jit-compile definition.
