m68k: if we have a symbol in the location reference, that will be base, so try to insert an index register instead, reduces the amount of data->address register shuffling in the generated code

m68k: while updating reference, don't reallocate and copy the index to another register if we can apply scaling for it and we don't need to multiply, so the maybe_const_reg doesn't change. this improves generated code when a const reg (eg: a loop counter) is used as array index

m68k: implemented t68kvecnode.update_reference_reg_packed. same as the generic one, but allocates int registers instead of address registers, because on 68k IMUL,SHR/SHL and AND can't work on address registers, which results in a lot of register shuffling
