The idea is to make this the model for future TypedArray methods.
A possible downside could be lower array method performance
if everything gets polymorhpic (but if enough inlining happens, it
should still be fast), but on the upside, this change means that
the TypedArray methods won't create as much code size bloat.

This patch:
- Refactors Parser::ParseVariableDeclarations
- Introduces Parser::PatternMatcher class
- Implements matching a single variable pattern
- Implements rudimentary matching against object literal pattern
as a proof of concept

Make the parser handle references to "this" as unresolved variables, so the
same logic as for the rest of function parameters is used for the receiver.
Minor additions to the code generation handle copying the receiver to the
context, along with the rest of the function parameters.

A strict arrow function with no parameters and no variable bindings
won't need a context object because it will never have any
locals. (This is unlike strict normal functions, which do have
"arguments" and "this" locals.)

This reverts commit 992751d0dc.
The final spec for Object.getPrototypeOf calls ToObject on the
parameter, which means that it should only throw for null and
undefined. For other non object values the prototype of the wrapper
should be used.
Difference from last time: Updated .status and will disable Blink
side tests as needed.

The prototype of a class constructor function is read only. When we set
computed property names we were ignoring this and we were overriding the
property.
Since the prototype is the only possible own read only property on the
constructor function object we special case this so we do not have to
check this for every property in the class literal.
