Based on actually using the IR when prototyping adding
type assertions, a few changes to improve it:
- Merge DeferStmt and GoStmt, since they are variants of one thing.
- Introduce LogicalExpr for && and ||, since they (alone) need an init list before Y.
- Add an explicit op to various constructors to make them easier to use.
- Add separate StructKeyExpr - it stores Value in a different abstract location (Left) than KeyExpr (Right).
- Export all fields for use by rewrites (and later reflection).
Passes buildall w/ toolstash -cmp.

The plan was always to export them once we remove the getters
and setters, but do it a bit early, with _ suffixes as needed, so that
the reflection-based ir.Dump can access the fields.
Passes buildall w/ toolstash -cmp.

Add Node method generator by Matthew Dempsky,
lightly adapted to account for a few special cases.
No more writing these by hand.
