0e8a1a40f2 Auto merge of #1294 - JOE1994:windows_instant, r=RalfJung 
Add support for 'std::time::Instant' in Windows

Add support for creating `std::time::Instant` in Windows

Includes shims for `QueryPerformanceCounter` & `QueryPerformanceFrequency` in Windows, which are both called in Windows when `std::time::Instant` is created.

Windows docs page ["Acquiring high-resolution time stamps"](https://docs.microsoft.com/en-us/windows/win32/sysinfo/acquiring-high-resolution-time-stamps) was helpful in learning how `QueryPerformanceCounter` & `QueryPerformanceFrequency` work.

`Machine` memory is not leak-checked, so if we forgot to deallocate part of the env shim memory, we wouldn't even notice. Thus add a dedicated memory kind that is leak-checked.

Abort instead of panic on asserting intrinsics

This fixes #1222
replacing the panic with an abort and a corresponding message.
the stack trace is already printed, this just adds an optional message the caller can pass, and I just pass the same message we passed to the panic but now to the abort instead.

Add directory-related shims

This PR adds support for `mkdir`, `rmdir`, `opendir`, `closedir`, and `readdir64_r`.

Open directory streams are tracked through a HashMap indexed by pointer locations, which holds directory iterators. Since `DIR` is an opaque type in glibc, I represent them with 1-byte allocations, and then just use their pointers in HashMap lookups.

Tests are included to exercise the new functionality.

Reorganize shims by platform

Fixes https://github.com/rust-lang/miri/issues/1161. I am currently testing which shims belong to which platform. If you are reading this and know the answer for any of those please write me :P

Add shim for rename

This adds a straightforward shim for rename, which is used by `std::fs::rename`. Testing is included.

As a heads up, I expect one or two merge conflicts between my PRs, since some of them touch the same `use` statements, or add items near the same places. I'll rebase and fix them as they come up.
