This updates to 0.1.13 for `compiler_builtins`, published to fix a few
issues. The feature changes here are updated because `compiler_builtins`
no longer enables the `c` feature by default but we want to do so
through our build still.
Closes#60747Closes#60782
Remove bitrig support from rust
Resolves#60743
using `find` and `rg` I delete every occurence of "bitrig" in the sources, expect for the llvm submodule (is this correct?).
There's also this file 5b8e99bb61/rls-analysis/test_data/rust-analysis/libstd-af9bacceee784405.json which contains a bitrig string in it. What to do with that?
Allow subdirectories to be tested by x.py test
Fixes https://github.com/rust-lang/rust/issues/60718.
As far as I can tell, multiple `--test-args` flags are ignored (only the first is respected), so if you specify a subdirectory, you won't also be able to filter using `--test-args`. If you don't specify a subdirectory, `--test-args` will continue working as usual, so this is strictly an improvement on the current state of affairs.
use SecRandomCopyBytes on macOS in Miri
This is a hack to fix https://github.com/rust-lang/miri/issues/686: on macOS, rustc will open `/dev/urandom` to initialize a `HashMap`. That's quite hard to emulate properly in Miri without a full-blown implementation of file descriptors. However, Miri needs an implementation of `SecRandomCopyBytes` anyway to support [getrandom](https://crates.io/crates/getrandom), so using it here should work just as well.
This will only have an effect when libstd is compiled specifically for Miri, but that will generally be the case when people use `cargo miri`.
This is clearly a hack, so I am opening this to start a discussion about whether we are okay with such a hack or not.

PGO: Add a run-make test that makes sure that PGO profiling data is used by the compiler during optimizations.
From the tests comment section:
```
# This test makes sure that PGO profiling data leads to cold functions being
# marked as `cold` and hot functions with `inlinehint`.
# The test program contains an `if` were actual execution only ever takes the
# `else` branch. Accordingly, we expect the function that is never called to
# be marked as cold.

bootstrap: use correct version numbers for llvm-tools and lldb
The current URLs for the `llvm-tools` and `lldb` components are a bit broken right now:
```
https://static.rust-lang.org/dist/2019-04-25/llvm-tools-1.34.1 (fc50f328b 2019-04-24)-aarch64-unknown-linux-gnu.tar.gz
```
This PR uses proper version numbers for those. Tested a dist build locally and everything works.

Add codegen test for PGO instrumentation.
This PR adds a codegen test that makes sure that LLVM actually generates instrumentation code when we enable PGO instrumentation in `rustc`.
The second commit updates a test case to the new commandline option syntax introduced in #59874. Without the fix the test still works, but it confusingly creates a directory called `test.profraw`, which usually is the name of the _file_ where profiling data is collected.
Revert "compile crates under test w/ -Zemit-stack-sizes"
Revert PR #59401 to fix issue #59652 (a stable-to-beta regression).
This is result of squashing two revert commits:
Revert "compile all crates under test w/ -Zemit-stack-sizes"
This reverts commit 7d365cf27f.
Revert "bootstrap: build compiler-builtins with -Z emit-stack-sizes"
This reverts commit 8b8488ce8f.
----
(My intention is that someone can re-add this code again later, either after the `ld.gold` issue itself is fixed, or with safe-guards to check whether `ld.gold` is in use and then issuing warnings about the problems here when they arise.)

Support using LLVM's libunwind as the unwinder implementation
This avoids the dependency on host libraries such as libgcc_s which
may be undesirable in some deployment environments where these aren't
available.
