commit 6cebf7d963c18e2ab09f2320c949baf0a4bed721
Author: ulan <ulan@chromium.org>
Date: Sun Aug 07 15:33:36 2016

Unify memory optimization modes and flags.

This patch folds --optimize-for-size flag and check for low-memory device
into Heap::ShouldOptimizeForMemoryUsage() predicate.

It has the following side effects:
- the heap growing factor for low-memory devices is capped at 1.3 (old value was 2.0).
- the memory reducer will be more aggressive for low-memory devices.
