allocate free variables inline to closures
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/programs.h (SCM_PROGRAM_FREE_VARIABLES)
(SCM_PROGRAM_FREE_VARIABLE_REF, SCM_PROGRAM_FREE_VARIABLE_SET)
(SCM_PROGRAM_NUM_FREE_VARIABLES):
* libguile/programs.c (scm_make_program, scm_program_num_free_variables)
(scm_program_free_variable_ref, scm_program_free_variable_set_x):
Allocate free variables inline with programs, instead of being in a
vect. Should improve locality, and require fewer local variables in
the VM.
* libguile/vm-engine.c (vm_engine): Remove free_vars and free_vars_count
variables.
* libguile/vm-engine.h (CACHE_PROGRAM): No need to muck with free_vars
and free_vars_count.
(CHECK_FREE_VARIABLE): Update for inline free vars.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Update for inline free
vars.
(make-closure, fix-closure): Take the closure vals as separate stack
args, and copy or fix them inline into the appropriate closure.
* module/language/objcode/spec.scm (program-free-variables): Define a
local version of this removed function.
* module/language/tree-il/compile-glil.scm (flatten): Adjust to not make
a vector when making closures.
* module/system/vm/program.scm: Export program-num-free-variables,
program-free-variable-ref, program-free-variable-set!, and remove
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update to not make vectors
when making closures.
