4e1a3c5f2d syntax bug fixed
syntax like:
var f=func(){}
(var a,b,c)=(1,2,3);
will be incorrectly recognized like:
var f=func(){}(var a,b,c)

this bug is fixed now.

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.

aae9395d66 bug fixed
add operand op_offset to make sure arguments are loaded at correct places,before this commit,arguments are not loaded from a correct offset,which will cause SIGSEGV when calling a function that has complex closure
