4a7c70de23 Add zapping of Map contents in debug mode.
This zaps the contents of stale descriptor arrays and prototype
transition arrays before overwriting references to them. It should help
to discover accidental sharing early and is needed for the heap verifier
when map collection with incremental marking lands.

it is safe to make calls to GetConstructorName and further to

  - heap profiler now makes one pass less over the heap.
  - HeapEntriesMap does not allocate EntryInfo per each entry.
  - there's no need for an extra pass to set indexes before serialization.

As a result snapshot taking time has reduced up to 2x times.

e443c69b8d MIPS: Reduce size of LIR instruction by one word and remove dead code.
Port r11454 (72c662fc)

Original commit message:
Reduce size of LIR instruction by one word and remove dead code.

Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.

This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.

Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

b8c63a576e Bumped bootup memory limit on 32bit platforms using snapshot.
Somehow the mmaps we do look the same, but the info in the proc FS tells us that
we use a bit more memory. I am not sure if this is a real issue or not, but this
CL should at least get the build bots green again...
