tests: Fix overflow-checks test for RISC-V target

The overflow-checks codegen test was failing on riscv64gc target
because the FileCheck pattern did not account for ABI extension
attributes. RISC-V LP64 ABI requires integer types smaller than
XLEN (64-bit) to be zero-extended or sign-extended to register width.

For u8 parameters, RISC-V generates:
  i8 noundef zeroext %a, i8 noundef zeroext %b

While x86_64 and aarch64 generate:
  i8 noundef %a, i8 noundef %b

The original CHECK pattern only matched the format without the
`zeroext` attribute, causing test failures on RISC-V.

This patch makes the zeroext attribute optional in the FileCheck
pattern using `{{( zeroext)?}}`, allowing the test to pass on
architectures that add ABI extension attributes (e.g., RISC-V).

Test results before fix:
- x86_64-unknown-linux-gnu: 3 passed
- aarch64-unknown-linux-gnu: 3 passed
- riscv64gc-unknown-linux-gnu: 1 passed, 2 failed

Test results after fix:
- x86_64-unknown-linux-gnu: 3 passed
- aarch64-unknown-linux-gnu: 3 passed
- riscv64gc-unknown-linux-gnu: 3 passed

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).

Quick Start

Read “Installation” from The Book.

Installing from Source
