Fix `--nocapture` for run-make tests This was confusing because there are three layers of output hiding. 1. libtest shoves all output into a buffer and does not print it unless the test fails or `--nocapture` is passed. 2. compiletest chooses whether to print the output from any given process. 3. run-make-support chooses what output to print. This modifies 2 and 3. - compiletest: Don't require both `--verbose` and `--nocapture` to show the output of run-make tests. - compiletest: Print the output from `rmake` processes if they succeed. Previously this was only printed on failure. - compiletest: Distinguish rustc and rmake stderr by printing the command name (e.g. "--stderr--" to "--rustc stderr--"). - run-make-support: Unconditionally print the needle/haystack being searched. Previously this was only printed on failure.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
