Track field types.

This is an initial step towards tracking the exact types instead of just the representations of fields. It adds support to track up to one map of heap object field values, eliminating various map checks on values loaded from such fields, at the cost of making stores to such fields slightly more expensive.

Reland "More tests for Union & Intersect"

Fixes size approximation in Intersect. Also lowers the number of fuzzed types in test, to address time-outs.

Parser cleanup: PreParser doesn't need to produce symbol data any more.

State of the art:
- Chromium doesn't do a separate preparsing phase any more.
- We start parsing with Parser, and when it sees a lazy function, it falls back
to PreParser for that function.
- The symbol data should contain symbols which are *outside* lazy functions.
- So Parser should always produce symbol data, and PreParser should never.
- Because it's this simple now, we don't need to keep track of "should
produce symbol data" (i.e., whether we're inside a lazy func or not).

Some tests and simplified TransitionArray copying

Tests for verifying that we deal correctly with shrinking transition
arrays while allocating a copy of one.

Also, we can rely on a transition array only shrinking and not
disappearing during gc while copying one.
