Description

MIPS: Reland "Track field types.". Port r20746 (09f9176) Original commit message: 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. Issues with transitioning stores and fast object literals in Crankshaft fixed. TEST=mjsunit/field-type-tracking BUG=
