47acece7aa Auto merge of #1636 - RalfJung:rustup, r=oli-obk 
remove miri-rustc-tests

`@oli-obk` I am not sure if anyone used this program in the last few years. There are no instructions for how to use it. So I think keeping it working is just a waste of time. It now fails to build:
```
error[E0046]: not all trait items implemented, missing: `visit_foreign_item`
  --> src/bin/miri-rustc-tests.rs:36:17
   |
36 |                 impl<'tcx, 'hir> itemlikevisit::ItemLikeVisitor<'hir> for Visitor<'tcx> {
   |                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ missing `visit_foreign_item` in implementation
```
So I propose instead of me trying to figure out how to fix this, we just drop this ancient code.

update README

Data races are detected now, but also the amount of non-determinism went way up so reword that point.

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

6c5722933e Fix typos - looked into the papers handling of timestamps, after looking into it again, it seems the paper only increments the timestamp after release operations, so changed to approximation of that implementation. 2020-11-28 17:17:07 +00:00

cdb7adb4b3 Make weak syscalls in std work. 
std now looks up `getrandom` and `statx` with `dlsym` before attempting
to use `syscall(SYS_.., ..)`.

It also now passes all arguments as a machine-sized word, instead of
their original types.
