A function that has no prologue cannot be reasonably expected to support debuginfo. In fact, the existing code (before this patch) would generate invalid instructions that caused crashes. We can solve this easily by just not emitting the debuginfo in this case. Fixes rust-lang#42779 cc rust-lang#32408
This pulls in a fix for the install script on some tr(1) implementations, as well as an update to use `anyhow` instead of `failure` for error handling.
Keep congruency with other parts, full word vector is rarely used.
When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system. However, since we pass cmake defines to set the compiler and target, LLVM still compiles these tools for the target system, rather than the host. The tools then fail to execute during the LLVM build. This change sets defines for the tools that need to run on the host (llvm-nm, llvm-tablegen, and llvm-config), so that the LLVM build does not attempt to build them, and instead relies on the tools already built. If compiling with clang-cl, this change also adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for cross-compilation.
Other terms are more inclusive and precise. Clippy still has a lint named "blacklisted-name", but renaming it would be a breaking change, so is left for future work. The target configuration option "abi-blacklist" has been depreciated and renamed to "unsupported-abis". The old name continues to work.
adjust ub-enum test to be endianess-independent @cuviper noted that our test fails on "other" endianess systems (I never know which is which^^), so let's fix that.

Fix cross compilation of LLVM to aarch64 Windows targets When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system.

If compiling with clang-cl, adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for each cross-compilation target.

Avoid "blacklist" Other terms are more inclusive and precise. Clippy still has a lint named "blacklisted-name", but renaming it would be a breaking change, so is left for future work. The target configuration option "abi-blacklist" has been depreciated and renamed to "unsupported-abis". The old name continues to work.
…r=Mark-Simulacrum Fix x.py test for librustc crates. rust-lang#73352 introduced a bug where `x.py test src/librustc_ast` would fail to actually run the tests. The issue is that `krate` and `all_krates` were changed to return relative paths. This caused the code to do a test of "relative_path ends with absolute path" which is always false. The solution is to swap that around. The change to `Crate` isn't necessary, it just simplifies the code and makes it uniform with `CrateLibrustc`.
