mimalloc is a compact general purpose allocator with excellent performance.
I pre-allocate a large block of memory using mmap, for example, 1GB, and then use the mi_manage_os_memory function to manage this block of memory. After that, I allocate several memory...

1. GCC-4.8.5 does not contain the file stdatomic.h, add a similar file (gcc-4.8.5-atomic.h) for compiling in gcc4.8.5 2. Add option MI_ATOMIC_FOR_GCC485 in cmakelists.txt for this case
This can be useful if the code base already overrides it.

I'm hitting infinite recursion here when trying to run statically linked mimalloc from `dev3` with `MI_DEBUG_FULL=ON`+ `MI_CHECK_FULL=ON` on Android. Attaching top of the callstack: ``` _mi_heap_main_get (mimalloc/src/init.c:272) mi_prim_get_default_heap (mimalloc/include/mimalloc/prim.h:411) mi_malloc...
potential fix for https://github.com/microsoft/mimalloc/issues/1058 also needed in dev3
