also ignore 'thread leaks' with -Zmiri-ignore-leaks

This is a step towards https://github.com/rust-lang/miri/issues/1371. The remaining hard part would be supporting checking for memory leaks when there are threads still running. For now we elegantly avoid this problem by using the same flag to control both of these checks. :)

486b5dfe74 Auto merge of #1832 - hyd-dev:1776-follow-up, r=RalfJung 
Report an error if a `#[no_mangle]`/`#[export_name = ...]` function has the same symbol name as a built-in shim

Implements https://github.com/rust-lang/miri/pull/1776#issuecomment-821322605.

The error looks like this:
```
error: found `malloc` symbol definition that clashes with a built-in shim
  --> tests/compile-fail/function_calls/exported_symbol_shim_clashing.rs:12:9
   |
12 |         malloc(0);
   |         ^^^^^^^^^ found `malloc` symbol definition that clashes with a built-in shim
   |
help: the `malloc` symbol is defined here

  --> tests/compile-fail/function_calls/exported_symbol_shim_clashing.rs:2:1
   |
2  | / extern "C" fn malloc(_: usize) -> *mut std::ffi::c_void {
3  | |     //~^ HELP the `malloc` symbol is defined here
4  | |     unreachable!()
5  | | }
   | |_^
   = note: inside `main` at tests/compile-fail/function_calls/exported_symbol_shim_clashing.rs:12:9
```

This does not implement "better error messages than we do currently for arg/ABI mismatches" in https://github.com/rust-lang/miri/pull/1776#issuecomment-821343175 -- I failed to remove all `check_arg_count()` and `check_abi()` (they are still used in `src/shims/intrinsics.rs` and `call_dlsym()`) and they don't receive the name of the shim.

d473242ecd Auto merge of #1617 - JCTyblaidd:data_race_detector, r=RalfJung 
Add simple data-race detector

Partially fixes data-race detection, see #1372, based on Dynamic Race Detection for C++11

- This does not explore weak memory behaviour, only exploring one sequentially consistent ordering.
- Data-race detection is only enabled after the first thread is created, so should have minimal overhead for non-concurrent execution.
- ~~Does not attempt to re-use thread id's so creating and joining threads lots of time in an execution will result in the vector clocks growing in size and slowing down program execution~~ It does now
