c0934e1eca Auto merge of #1152 - divergentdave:shim-directory, r=RalfJung 
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.

e530829797 Use 'cargo check' to build the sysroot and target crate 
Fixes #1057

Since we are no longer using "cargo rustc", we now use the rustc
arguments passed by Cargo to determine whether we are building a
build dependency, normal dependency, or "target" (final binary or test)
crate.

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.

Add statx shim for linux target

This is an attempt to fix: https://github.com/rust-lang/miri/issues/999 (for linux only)

Currently there is one problem that I haven't been able to solve. `std::fs::metadata` fails because the creation time is not available even though it is provided in the shim code.

In order to inform the caller that the field was provided, the `stx_flag` field must have the bits of `STATX_BTIME` set (which they are). The creation time is in the `stx_btime` field of the `statx` struct (see [1]). The relevant code in `libstd` is here (probably?): https://github.com/rust-lang/rust/blob/master/src/libstd/sys/unix/fs.rs#L322

Another important point is that we are just providing the fields that are available in "all" platforms (this is, without using any platform specific traits or so). This can be improved later.

References:
[1] Man page: http://man7.org/linux/man-pages/man2/statx.2.html
[2] libc `statx` struct: https://docs.rs/libc/0.2.63/libc/struct.statx.html

Edit: The problem is that my filesystem is not providing it and I thought all filesystems could provide it. I changed the code so it only provides those dates if they are available. now we are ready to go.

Support unwinding after a panic 
Fixes #658

This commit adds support for unwinding after a panic. It requires a
companion rustc PR to be merged, in order for the necessary hooks to
work properly.

Currently implemented:
* Selecting between unwind/abort mode based on the rustc Session
* Properly popping off stack frames, unwinding back the caller
* Running 'unwind' blocks in Mir terminators

Not yet implemented:
* 'Abort' terminators

This PR was getting fairly large, so I decided to open it for review without
implementing 'Abort' terminator support. This could either be added on
to this PR, or merged separately.

Fix unchecked memory access for files

This PR takes care of two problems:

- It uses `Memory::(read|write)_bytes` to guarantee that memory accesses are checked (Fixes: https://github.com/rust-lang/miri/issues/1007)
- It removes the `(get|remove)_handle_and` methods which were a little bit cumbersome to use. In particular `remove_handle_and`, because we were using it to avoid borrowing issues before the `Evaluator::memory` field was public.
