Manual JIT interface via %jit-compile
* libguile/init.c (scm_i_init_guile): Call scm_init_jit ().
* libguile/jit.c (enter_mcode, exit_mcode): New static members; code
pointers for the JIT trampoline.
(emit_exit): New helper. The Lightning tramp/frame mechanism that we
use needs to exit via a jmp instead of a return. Adapt callers of
jit_ret.
(emit_entry_trampoline): Use the "frame" mechanism to enter the JIT.
(compile1): Add missing "break" after case statements. Oops!
(compile): Add prolog and "tramp" to compiled functions.
(initialize_jit): New local routine to init the JIT on demand.
(compute_mcode): New helper, to compile a function.
(scm_sys_jit_compile): New function, exported to Scheme as
%jit-compile.
(scm_jit_compute_mcode): Return the existing mcode if the function is
at the start.
(scm_jit_enter_mcode): Call the enter_mcode trampoline.
* libguile/jit.h (struct scm_jit_state): Declare, so we can make
pointers to it.
* libguile/threads.h (struct scm_thread): Add jit_state member.
* libguile/threads.c (on_thread_exit): Free the jit state.
