1960807 - [meta] Make the buffer allocator into a more general purpose allocator and use it in more places

Status: NEW

(Core :: JavaScript: GC, enhancement, P3)

Description

[Jon Coppeard (:jonco)]

The plan for the buffer allocator is to use it to replace jemalloc for allocations attached to GC things. This will improve efficiency, e.g. by reducing the amount of locking we need to do on allocation.

To do this we need to remove some of its current restrictions and make it into a more general purpose allocator. Then we need to migrate existing code to make use of it.
