Well, it would change source-level next and step too if we didn't have the disassembler.  When we're doing a source-level step/next, we look at the stream of instructions and when we have a block of non-branching instructions, we put a breakpoint after the block and continue, instead of instruction stepping.  We use the disassembler to detect instructions that can branch.  source level step and next would still work, but they would be a bit slower.
