dddeb98df9 Parser & internalization fix: ensure no heap allocs during GetString(Handle<String>). 
The bug has always been there: when the parser is operating in the "immediately
internalize" mode and calls GetString, we get FlatContent of a string and then
do heap allocation.

The bug was uncovered by https://codereview.chromium.org/693803004/ (which put
the parser to the "immediately internalize" mode more often), but looking at the
code, it's possible that it can happen in other cases too.

This CL makes AstValueFactory handle this situation gracefully: it won't try to
internalize inside GetString(Handle<String>); it's unnecessary anyway since we
have the Handle<String> already.

65f4716b3f Handle store buffer slot overwrite during object promotion. 
The bad scenario this fix handles:

We have a slot in a free list, then promote the object pointed-to by
the slot during scavenge. When allocating the space for the promoted
object, we overwrite the slot with the free list entry map if the
object is allocated just before the slot. After the allocation,
ScavengingVisitor::PromoteObject overwrites the slot with the
address of the allocated object, thus corrupting the free list.

Unfortunately, we do not have a way to construct a reliable repro
case because we would need to somehow craft a free list and store
buffer slot to be in the right configuration.

This contains the following changes squashed together:
- Switch BasicBlock::loop_end to be a basic block instead of an RPO.
- Switch ScheduleLate to use dominator depth instead of RPO.
- Switch ScheduleEarly to use dominator depth instead of RPO.
- Push out absolute RPO ordering everywhere else in the scheduler.
- Keep linked list of blocks in RPO order while scheduling.
- Switch from RPO number to depth for dominator calculation.

0b9a70ade3 Remove --harmony implications for incomplete features 
This is in preparation for making --harmony and --es-staging synonyms.
The only remaining difference currently is block-scoping, which is still
implied by --harmony, to avoid regressing on a long-available feature.

Also removes the special-casing of --harmony-proxies.

94a08565d7 Parser & internalizing: efficiency fixes. 
1) In ParseLazy, we're already using the heap, so we can also tell
AstValueFactory to internalize immediately. This is more efficient.

2) No need to collect the values in values_ and strings_ if they're already
internalized.

3) No need to collect AstValues which are strings in values_ since they don't
need to be internalized (the underlying strings will be internalized
separately).
