…er (facebook#1504) Summary: Large segment needs to be backed by a large storage size. StorageProvider currently always allocate fixed size of storage determined by HERMESVM_LOG_HEAP_SEGMENT_SIZE. This diffs adds support of allocating larger storage with below changes: 1. `newStorage()` and `deleteStoragr()` takes addition `sz` parameter. 2. For `MallocStorageProvider` and `VMAllocateStorageProvider`, simply change the previous fixed storage size to passed in `sz`. 3. For `ContiguousVAStorageProvider`, use a BitVector to manage allocations and deallocations. This can be improved later if we observe fragmentations. The support of enabling different sizes of heap segment will be added later. Differential Revision: D61676721

Summary:
Large segment needs to be backed by a large storage size.
StorageProvider currently always allocate fixed size of storage
determined by HERMESVM_LOG_HEAP_SEGMENT_SIZE.
This diffs adds support of allocating larger storage with below
changes:
newStorage()anddeleteStoragr()takes additionszparameter.MallocStorageProviderandVMAllocateStorageProvider, simplychange the previous fixed storage size to passed in
sz.ContiguousVAStorageProvider, use a BitVector to manageallocations and deallocations. This can be improved later if we observe
fragmentations.
The support of enabling different sizes of heap segment will be added
later.
