Refactor code such that the linear algorithm is actually executed
outside the method for the fixpoint iteration. Also added a CHECK
which verifies that iterating the ephemerons one more time results in
no further marked objects.

Also force another iteration when ProcessMarkingWorklist() processed
some object. In such cases we need to re-process all ephemerons
otherwise ephemeron semantics might be broken.

When preparing to take a heap snapshot for the devtools, V8 uses
CollectAllAvailableGarbage, which runs 2 to 7 rounds of garbage
collection, depending on whether weak callbacks indicate that further
rounds might be beneficial. Depending on how many rounds of GC run,
varying amounts of bytecode and baseline code may be flushed, leading to
inconsistent behavior and underreporting the amount of memory used by
bytecode and baseline code. In this change, I propose that bytecode
should not increase in age during these collections, so that the
resulting snapshot is a better indication of actual memory usage.

In particular, the logic for CharacterClassEscape, ClassEscape,

This CL refactors related logic to have only a single implementation.

As a drive-by, fix one related inconsistency related to \k inside

Several of the cctest/test-bytecode-generator/* tests used to rely
on the __COUNTER__ C++ compiler macro, which could cause spurious
test failures due to mismatched expectations when usages of that
macro were added or removed elsewhere in the code. This patch switches
to a custom, controllable static counter variable instead, to make
the tests' behaviors self-contained.
