Tracking Issue for RFC 2959: Promote aarch64-unknown-linux-gnu to a Tier-1 Rust target

[pietroalbini]

This is a tracking issue for the RFC "Promote aarch64-unknown-linux-gnu to a Tier-1 Rust target" (rust-lang/rfcs#2959).

Steps:

• Tier Promotion PR
  • PR: Promote aarch64-unknown-linux-gnu to Tier 1 #78228
• Implement stack probes for the aarch64-unknown-linux-gnu target
  • Tracking issue: Support stack probing for arm64 (aarch64) #77071

[pietroalbini]

The PR promoting the target to Tier 1 was just merged! The target is on track to be Tier 1 in Rust 1.49.0!

Visited during the compiler team tracking issue triage. We're closing this issue since aarch64-unknown-linux-gnu is already Tier 1 and advertised as such. The open issue regarding stack probe support has its own dedicated tracking issue so there's nothing left to do here.
