LibJS: Make sure all allocators are 8-byte aligned

Browse Source 
Absolutely massive allocations > 1024 bytes would go into the size
class which was 3172 bytes. 3172 happens to not be 8 byte aligned, and
so made UBSAN very sad on x86_64. Change the largest allocator to be
3072 bytes, which is in fact a multiple of 8 :^)
