0d5b0fa57d now local values are stored on stack. upvalue is generated when creating a new function in local scope. 
may include some bugs inside. but all test files has passed the test so i decide to push it.

166fe32839 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

a3d629a08e 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.
