TASK: port LLVM dependents to llvm-20, drop llvm19

[yselkowitz]

What does the ELN SIG need to do?

• Pursuant to https://fedoraproject.org/wiki/Changes/LLVM-20, the llvm package is going to be updated to 20.1, and an llvm19 compat package created. Once that much is done, it will be up to maintainers of LLVM-dependent packages to port their packages from 19 to 20. (In the past, we've helped with this in order to expedite dropping the compat version from ELN.) In the meantime, llvm19 will be temporarily added to ELN until all dependencies have been ported.

llvm18/clang18 removal is blocked by #207.

Status: https://tiny.distro.builders/view-rpm--view-eln--llvm19-libs.html

ELN

• annobin
• bcc
• bpftool
• bpftrace
• kernel (perf)
• mesa
• qt6-qttools
• rust

ELN Extras

• kdevelop
• qt5-qttools

llvm19 and llvm-20 are being built now. mesa was upgraded to 20 in tandem, but not the rest.

[yselkowitz]

annobin, bcc, bpftool, and qt6-qttools should just need a revbump and rebuild. (Hopefully kernel will be the same.)

bpftrace needs a new release: bpftrace/bpftrace#3840

rust is targeting migration for 1.87.0 (now in nightly): rust-lang/rust#135763

https://src.fedoraproject.org/rpms/rust/c/3436f8c99bd742015560fadea6d2b0e02e631145?branch=rawhide, once it hits ELN, will update rust to llvm-20.
