Use abstract configurations to switch between opt debug settings

The problem is that conditions are evaluated before configuration inheritance is resolved, so we can't just define a configuration like this:

'Optdebug': {
  'inherits_from': ['Debug'],
  'variables': {
    'v8_optimized_debug': 2,
  }
}

Instead, we have to put the different settings depending on the optimization level into separate configurations, and use conditions inside the concrete configurations to inherit from the correct base class.

Common settings go in the base configuration DebugBaseCommon, and v8_optimized_debug dependent settings go into DebugBase{0,1,2}

The new Debug configuration inherits from DebugBaseCommon and DebugBase<(v8_optimized_debug), while the new configuration Optdebug inherits from DebugBaseCommon and DebugBase2.

OrderedHashTable implementation with Set and Map interfaces

OrderedHashTable is an insertion-ordered HashTable based on
Jason Orendorff's writeup of a data structure attributed to Tyler Close:
https://wiki.mozilla.org/User:Jorend/Deterministic_hash_tables

It is intended as the new backing store for JSSet/JSMap, as ES6 requires
insertion-order-based iteration. Note, however, that in the interest of
keeping the initial check-in small this patch does not yet include any
iteration support.

This change also doesn't yet touch any existing behavior, but in
a branch I've verified that these structures pass the existing
JSSet/JSMap mjsunit tests.

Update tests to use the new compilation API + related fixes.

Esp. get rid of PreCompile in tests, as it's going to be removed.

Notes:
- The new compilation API doesn't have a separate precompilation phase, so there
is no separate way to check for errors except checking the compilation
errors. Removed some tests which don't make sense any more.
- test-api/Regress31661 didn't make sense as a regression test even before the
compilation API changes, because Blink doesn't precompile this short scripts. So
detecting this kind of errors (see crbug.com/31661 for more information) cannot rely
on precompilation errors.
- test-parsing/PreParserStrictOctal has nothing to do with PreParser, and the comment
about "forcing preparsing" was just wrong.
- test-api/PreCompile was supposed to test that "pre-compilation (aka
preparsing) can be called without initializing the whole VM"; that's no longer
true, since there's no separate precompilation step in the new compile
API. There are other tests (test-parsing/DontRegressPreParserDataSizes) which
ensure that we produce cached data.
- Updated tests which test preparsing to use PreParser directly (not via the
preparsing API).
- In the new compilation API, the user doesn't need to deal with ScriptData
ever. It's only used internally, and needed in tests that test internal aspects
(e.g., modify the cached data before passing it back).
- Some tests which used to test preparse + parse now test first time parse +
second time parse, and had to be modified to ensure we don't hit the
compilation cache.
