bors 57786678d4 Auto merge of #1975 - DrMeepster:backtrace_fix, r=RalfJung ...

Make backtraces work with #[global_allocator]

Currently, backtraces break when the global allocator is overridden because the allocator will attempt to deallocate memory allocated directly by Miri.

~~This PR fixes that by using a new memory kind and providing a function to deallocate it. We can't call the custom allocator to allocate because it's not possible to call a function in the middle of a shim.~~

This PR fixes that by adding a new version of the backtrace API accessible by setting `flags` to 1. Existing code still functions.
