This is a preparation for removing aggregated heap snapshots.
W/o this API, counting object instances in a snapshot is very hard.

There were some changes in ARM r8172 that we needed to port to MIPS,
but missed.

The bug was exposed with the Arm & Mips fix in r8321, "Fix wrong
parenthesis in stub ARM and MIPS generation code."

with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

In simple unconditional loops - like the following - the hydrogen stack check elimination did not detect the call as the loop header block itself was not considered.

This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

Added tests for escapes and for not allowing line-terminators betwen "native" and "function".

We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

I think the problem did not manifest as a bug, since the only
consequence was to generate extra code to return heap number
results in case of the INT32-stub.
