Tracking Issue for `no-jump-tables`

[tgross35]

This is a tracking issue for the -Zno-jump-tables compiler flag

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Steps

• Implement the RFC Add -Zno-jump-tables #105812
• Adjust documentation (see instructions on rustc-dev-guide)
  • Unstable docs: Add unstable book page for the no-jump-tables codegen option #116593
• Formatting for new syntax has been added to the Style Guide (nightly-style-procedure) (N/A)
• Stabilization PR Stabilize -Zno-jump-tables into -Cjump-tables=bool #145974

Unresolved Questions

• Should this be -Zjump-tables=false? C compilers accept both -fjump-tables and -fno-jump-tables. #rust-for-linux > Stabilizing `-Zno-jump-tables`? @ 💬

Implementation history

• Implementation: Add -Zno-jump-tables #105812

I didn't see a tracking issue for #105812 so I created this one. cc @ojeda

Some zulip discussion about stabilization #rust-for-linux > Stabilizing `-Zno-jump-tables`?.

I brought up one concern there that I'll copy to the top post, this should probably be -Zjump-tables=false rather than using the C compiler flag -fno-jump-tables (since -fjump-tables works as well).
