Patch from Balazs Kilvady <kilvadyb@homejinni.com>.

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.

Notes:
- This makes Parser and PreParser produce the same errors with the added test
cases (this was not the case before).
- ParseBlock already does Expect(Token::LBRACE), so no need to check it twice.

ES6 makes the Function object properties "length" and "name"
configurable; switch the implementation over to follow that.

Doing so exposed a problem in the handling of non-writable, but
configurable properties backed by foreign callback accessors
internally. As an optimization, if such an accessor property is
re-defined with a new value, its setter was passed the new value
directly, keeping the property as an accessor property. However, this
is not correct should the property be non-writable, as its setter will
then simply ignore the updated value. Adjust the enabling logic for
this optimization accordingly, along with adding a test.

This also makes the "delayed strict mode violations" mechanism in PreParser
unnecessary.

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.
