* Cleanup defineOwnPropertyLars Knoll2018-06-261-5/+10
| | | | | | | | | | | | | | | | Make it a vtable method as required by the ES7 spec. Change all calls sites to call through the virtual function. Adjust ArgumentsObject and give it it's own defineOwnProperty implementation instead of hacking it into the base implementation. Move the array object specific handling into a reimplementation.

* Add Proxy support for prototype handlingLars Knoll2018-06-251-3/+10
| | | | | | | | | | | | | | Cleanup get/setPrototypeOf and fix some smaller incompatibilities in the default implementation for Object. Add the methods to the vtable and reimplement them according to spec for ProxyObjects. Clean up the Object.prototype.get/setPrototypeOf/__proto__ methods and fix a smaller bug in the Reflect API for those methods.

* garbage collect InternalClassLars Knoll2018-04-121-1/+1
| | | | | | | | | | | | | | | | Internal classes are now allocated and collected through the GC. As they are important to the deletion of other objects (because of the vtable pointer living inside the internal class), they need to get destroyed after regular objects have been sweeped. Achieve this by using a separate block allocator for internal class objects. Our lookups do often contain pointers to internal classes, so those need to be marked as well, so we don't accidentally collect them.

This now fixes that and introduces a unique ID that completely describes the state of the object including all it's prototypes. This opens up for optimizing lookups down to one branch and a load, independent of the depth of the value inside the prototype chain.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that not using any inline property storage comes at a relatively high price in terms of memory consumption, as we always need to also create a memberData for any object. This avoids the memberData creation in quite a few cases, as we use the additional padding we have up to the 32 byte boundary given by the memory manager to store some property data. This complicates property access somewhat. To avoid performance regressions because of this, add specialized QV4::Lookup functions that optimize for properties that are inline or in the memberData struct. Change seems to be performance neutral on v8-bench on x86_64, but reduces peak memory usage when running the benchmark by around 20%.
