0f94c96cbc Test for wrong arguments object materialization.
The test demonstrates a bad interaction between arguments object
materialization, escape analysis and exception handling.

We can return a wrong arguments object if we materialize arguments
object (using f.arguments) and then throw around f's frame so that f
does not clean up the materialized frame information (see the
MaterializedObjectStore in deoptimizer.h/.cc). If we enter another
function that has the same frame pointer and request an arguments object
of (or lazily deoptimize) that function, we can get the materialized
object of the original function.

We should clean up the materialized object store when we unwind the
stack.

3c3ce1bca8 Parser: Fix crash on stack overflow when lazy-parsing arrow functions
The problem manifests itself when parsing manages to return something
meaningful in the presence of a stack overflow. This happens because
calling ParserBase::Next() will still return one valid token on stack
overflow, before starting to return invalid tokens.

Take the following input as example:

        a.map(v => v + 1);
              | |
       already   next token
        parsed   (which will be an invalid token
  (identifier)   because of a stack overflow)

The "v" may have been already parsed into a VariableProxy, then if a
stack overflow occurs, next token will be an invalid token (instead
of Token::ARROW), but the parser will return the VariableProxy.

This always happens when lazy-parsing arrow functions, so the position
in the input stream where the the arrow function code ends is known.
This fix adds a check that ensures that parsing ended at the end
position of the arrow function.

86b391ecad Delegate throwing in RegExpExecStub to CEntryStub.
This ensures that there is only one stub that deals with unwinding the
stack. Having more than one place containing that logic is brittle and
error prone, especially when it is a corner case only for RangeErrors.

f6cd009efd ES6: Make function name configurable
Function name property is now standardized in ES6. It was a Mozilla proprietary
extension before. With ES6, the property was made configurable, so that it can
be used instead of another proprietary property, displayName.

This is a revert of revert c791d84112.

Last time this broke a Chrome browser test which has since been updated:

91b87e7a28 Do not create unresolved variables when parsing arrow functions lazily
Arrow function parameter lists are parsed as expressions. When an identifier
is found a VariableProxy is created and added to the list of unresolved
variables for the scope. When parsing a function lazily, the scope has been
already resolved, so with this patch only the VariableProxy is created,
without adding it as an unresolved variable in the scope.

54570cfa74 PPC aftermath: Fix regress-crbug-178790.
The test fails on XP only, so let's tentatively raise the stack limit more. We probably need to investigate what a tighter limit might be and (more importantly) what the underlying reason for the failure is.

Hopefully 1800kB is enough, we can't test this via try jobs, because we don't have XP try bots. :-/

978f41a1da RegExpParser: Fix Reset()ting to the end.
The bug would occur when we try to Reset() to a position already at the end.

This happens e.g., when the regexp ends with \u. What used to happen in that
case: 1) Advance past \ and u (to the end) (which wouldn't increase next_pos_
enough) 2) Try to parse 4 hex digits 3) When that failed, Reset() to the
position which should've been at the end but wasn't.

To be able to properly Reset() to a position at the end, we need to allow
next_pos_ to move beyond the end (since position() is next_pos_ - 1).

Minimal repro case:

var r = /foo\u/
r.test("foou") // should be true, was false.

(Note that \u not followed by 4 hex didits should be interpreted as an identity
escape. It already worked unless \u was at the end of the regexp.)

9da4998204 Abort optimization in corner case.
The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.

6ac4de87a8 harmony-scoping: make assignment to 'const' a late error.
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

c3af691e72 [turbofan] Remove int32 narrowing during typed lowering.
With Int32Add we lose the int/uint distinction, so later, in simplified lowering we can make a wrong decision. E.g., see the attached test case, where we lower NumberAdd -> Int32Add because inputs are Uint32, but during simplified lowering we change the inputs to Int32, so we get a wrong result.

Simplified lowering will lower the NumberAdd operations anyway, so we should lose performance.
