42ea494cd6 Redo r19140 with better efficiency. 
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.

8150464209 Make strict more error messages about "eval" and "arguments" less specific. 
We used to have error messages which provide context, like "Variable name may
not be eval or arguments in strict mode", but for other illegal words we only
have non-context specific error messages like "Unexpected reserved word".

Providing the context makes the code unnecessarily complex, since every
individual place must remember to check for eval or arguments. This CL produces
a unified error message ("Unexpected eval or arguments in strict mode"), and puts
the error reporting to (Pre)Parser::ParseIdentifier.

Notes:

- The module feature is so experimental, that I decided to not allow "eval" or
"arguments" as module-related identifiers in the strict mode (even though this
check wasn't there before).

- Unfortunately, there were some inconsistencies, since it was the
responsibility of the caller of ParseIdentifier to check "eval" and "arguments"
and some places didn't have the check for no good reason. This CL is supposed to
keep backward compatibility and *not* introduce any new errors.

- ECMA allows "eval" and "arguments" as labels even in strict mode. (Syntax:
"LabelledStatement: Identifier : Statement", and no strict mode restrictions on
Identifier are listed.)

- Tests which compare error message strings will fail, and need to be updated.

14a90fcc57 Better tests for the Parser / Preparser unification. 
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.

f6d1a4fef1 Allow externalizing strings in old pointer space. 
This is what I think is a better solution to the "external strings in
old pointer space" problem. Basically, it is an issue because GC scans
all fields of objects in old pointer space and if the cached address
of the backing store is unaligned, it looks like a heap object, boom.

The solution here is to use short external strings when we externalize
a string in old pointer space, and when the address is unaligned.
Short external strings don't cache the address, so GC has no issues.

23cbf27e12 Tests for (pre)parse errors when "yield" is found in inappropriate places. 
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:
- PreParser was using an error "reserved_word" which doesn't exist in
messages.js. Changed it to "unexpected_reserved".
