3deea632f8 front end optimization&stack overflow prompt 
change parameter type to avoid unnecessary copies of string.
change stack depth from 65536<<4 to 16+(65536<<2).
now you could know stack overflow when it happens

8e29a3ec5b bug fixed & more efficient callfv 
I changed callfv's way of calling a function with arguments in vm_vec.
now callfv fetches arguments from val_stack directly,so it runs test/fib.nas from 2.4s to 1.9s.

delete operand callf,add operands callfv & callfh.

also,i check val_stack's top to make sure there is not a stack overflow.

a68bf85f04 bug fixed 
a gc bug which causes  fatal error.
add member value collect to make sure that nasal_val is not collected repeatedly.
use builtin_alloc in builtin function to avoid incorrect collection of value in use(gc_alloc).
change free_list to free_list[vm_type_size] to avoid too many calls of new/delete(but seems useless?)
but the most important thing is fixing this bug.
