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.

Several major changes:

1. Pull out the expand cases for BSWAP and CT* into a separate function,
   reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
   iterative.  It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.

Eliminate the need for ExpandOp to set 'needsanotheriteration', as it already

dynamically allocate plugin space as needed

Another folding problem: if a node r/w chain or flag, don't fold it if it
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.
