(UnboundScript).
- Add ScriptCompiler (which will later contain functions for async compilation).
This is a breaking change, in particular, Script::New no longer exists (it is
replaced by ScriptCompiler::CompileUnbound). Script::Compile remains as a
backwards-compatible shorthand for ScriptCompiler::Compile.
Passing CompilerOptions with produce_data_to_cache = true doesn't do anything
yet; the only way to generate the data to cache is the old preparsing API. (To
be fixed in the next version.)

Notes:
- The regexp in the ParseObjectLiteralComment was wrong, made it less wrong (
it's still wrong since trailing commas are not required / allowed).
- Change in logic: In case we have "get somekeyword() { }", the "somekeyword"
was not logged as a symbol by PreParser and not expected in the preparser data
by Parser. This is unnecessary complication; in other contexts where keywords
are allowed as identifiers, they are logged as symbols (see
ParseIdentifierName).

This feature makes it possible to associate data with a script and get it back
when the script is compiled or when an event is handled. It was historically
used by Chromium Dev Tools, but not any more. It is not used by node.js.
Note: this has nothing to do with the preparse data, despite the confusing name.
The preparse data is passed as ScriptData*.
Note 2: This is the same as r19616 ( https://codereview.chromium.org/184403002/ )

The Parser never used the symbol stream produced by the PreParser for anything
useful, due to a bug introduced 3.5 years ago by
https://codereview.chromium.org/3356010/diff/7001/src/parser.cc.
The bug is that calling Initialize on symbol_cache_ doesn't change its
length. So the length remains 0, and the "if" in Parser::LookupSymbol is always
true, and Parser::LookupCachedSymbol is never called and symbol_cache_ never
filled.
This bug also masked a bug that the symbol stream produced by PreParser doesn't
match what Parser wants to consume. The repro case is the following:
var myo = {if: 4}; print(myo.if);
PreParser doesn't log a symbol for the first "if", but in the corresponding
place, Parser consumes one symbol from the symbol stream. Since the consumed
symbols were never really used, this mismatch went unnoticed.
This CL also fixes that bug.

Notes:
- To be able to move the recursive descent functions to ParserBase one at a
time, we temporarily need routing functions from traits to Parser/PreParser,
since the recursive descent functions form a cyclic structure.
- PreParser used to always allow intrinsic syntax. After this CL, it depends on
allow_natives_syntax() which was already in ParserBase.
- This CL also decouples (Pre)ParserTraits better from (Pre)Parser, passing more
information as parameters, so that the Traits don't need to get it from
(Pre)Parser.

(Second try, with fixes. First try: https://codereview.chromium.org/149913006/ )
The long-term goal is to move all recursive descent functions from Parser and
PreParser into ParserBase, but first they need to be unified.
Notes:
- The functions moved in this CL: ParseIdentifier, ParseIdentifierName,
ParseIdentifierNameOrGetOrSet, ParseIdentifierOrStrictReservedWord.
- IOW, this CL removes Parser::ParseIdentifier and PreParser::ParseIdentifier
and adds ParserBase::ParseIdentifier, etc.
- Error reporting used to require virtual funcs; now error reporting is moved to
the Traits too, and ParserBase no longer needs to be virtual.
- I had to move PreParser::Identifier out of the PreParser class, because
otherwise PreParserTraits cannot use it in a typedef.

Still relevant parts of the original commit message:
Unify paren handling in Parser and PreParser.
It is only needed in (Pre)Parser::ParseExpressionOrLabelledStatement for not
recognizing parenthesized identifiers as labels and in
(Pre)Parser::ParseSourceElements for not recognizing a parenthesized string as
directive prologue.
Parser Expressions don't keep track of whether they're parenthesized, so
PreParser Expressions shouldn't either.

We need a way to assert that for a given source code snippet, an error *is*
produced or *is not* produced. Otherwise we might accidentally create new
errors or start accepting code which was previously not accepted. Just checking
that Parser and PreParser produce the same result doesn't cut it.

In addition:
- Fix: PreParser used to report an unexpected token one token too late when
ParsePrimaryExpression failed.
- Unified identifier handling (PreParser::GetIdentifier is now like Parser::GetIdentifier).
- Fix: PreParser used to produce "unexpected_token YIELD" errors when Parser
produced "unexpected_token_identifier"; fixed PreParser to match Parser.

This contains the following fixes:
- We had strict_reserved_word and unexpected_strict_reserved, which one to use
was totally mixed in Parser and PreParser. Removed strict_reserved_word.
- When we saw a strict future reserved word when expecting something completely
different (such as "(" in "function foo interface"), Parser reports unexpected
identifier, whereas PreParser used to report unexpected strict reserved
word. Fixed PreParser to report unexpected identifier too.
- Unified parser and preparser error locations when the name of a function is a
strict reserved word. Now both point to the name.

Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.
Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.
Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.
