rustc_codegen_llvm: Require `opt-level >= 1` for index-based loop

To make debugger stepping intuitive with `-Copt-level=0`. See the
adjusted `basic-stepping.rs` test.

This is kind of a revert of bd0aae92dc76d9, except we don't revert it,
we just make it conditional on `opt-level`. That commit regressed
`basic-stepping.rs`, but it was not noticed since that test did not
exist back then. I have retroactively bisected to find that out.

It seems messy to sprinkle if-cases inside of the
`write_operand_repeatedly()` so make the whole function conditional.

The test that bd0aae92dc76d9 added in
`tests/codegen/issues/issue-111603.rs` already use `-Copt-level=3`, so
we don't need to adjust the compiler flags for it to keep passing.

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).
