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
...
relegalizes the stuff it returns.
Add the ability to custom expand ADD/SUB, so that targets don't need to deal
with ADD_PARTS/SUB_PARTS if they don't want.
Fix some obscure potential bugs and simplify code.
