now that we have control over emission of the code, emit the code using nested

"if" statements (indenting it appropriately, of course) instead of using goto's.
This inverts the logic for all of the if statements, which makes things simpler

Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it
...
faster. This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).
It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change. Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.
This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.
