Introduce a PrototypeIterator class and use it for prototype access

The new pattern is that we first get the map of the root of the
prototype chain using Object::GetMapRoot() and then walk up the
prototype chain using Map::prototype().

Fix arm64 deoptimization from double registers (reverts r20613).
...
This reverts "ARM64: Use pair memory access in deoptimizer entry", r20613. It does not really make sense to micro-optimize the deoptimizer as it is the ultra-slow path. Moreover, the original code was easier to read (in addition to being correct).

Implement handling of arrow functions in the parser
...
Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.
Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.
The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.
Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.

Support ES6 Map and Set in heap profiler
...
Added special handling for Map and Set in the heap snapshot generator.
Extracted common base type from JSMap/JSSet similar to JSWeakMap/JSWeakSet.
After handling collection specific properties all collections are processed as regular JSObject to make sure all regular properties set on them are present in the heap snapshot.
