Fix a crash when copying array data

2015-10-20T06:47:42+00:00

Regression from 5.5. d()->arrayData->alloc can be larger, but
never smaller than the allocation of the other's array data.

Add method to convert identifiers back into QV4::String objects

2015-09-25T08:38:40+00:00

Allocating a new String for the Identifier is wasting both memory
and CPU. Let's rather extract it from the IdentifierTable.

Inline property data into the object

2015-09-22T08:19:53+00:00

Append the part of the objects property data that is
known ad instantiation time to the object itself and
by that avoid creating a separate MemberData. Saves
some memory and should speed up object creation.

Currently implemented only for Object and ArrayObject.

Replace getPropertyDescriptor with a getValueOrSetter call

2015-09-15T19:13:16+00:00

This one returns a pointer to a Value instead of a property.

Further reduce usage of Property

2015-09-15T19:13:07+00:00

Using Property * as return value is something I wanted to get rid of for
a long time. As this interferes with storing properties inline in the
Object, now is a good time to finally do the work :)

Simplify Object::getValue

2015-09-15T19:13:03+00:00

Object::getValue only needs the value/property getter. Because of this
it's enough to pass it the Value stored in the member/arrayData and the
property attributes. Like this we avoid the reinterpret_cast to a
Property pointer.
