llvm-toolchain-13: please backport Risc-V .insn directive support

[Simon Chopin]

See https://github.com/rust-lang/llvm-project/pull/121

This is required for rustc 1.59, which in turn is required for Firefox 100 and related tunderbird.

Here's a merge of llvm-toolchain-13 that includes this patch, along with another one for https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-13/+bug/1973041

Build in progress there:

Refreshed version of the same thing, with the merge fixed, adding Replaces/Breaks fields due to the Ubuntu/Debian divergence on which package ships the new static libraries.

I used the dh-exec mechanism for the i386 exception as it is what is used in the current Salsa 13 branch for their grpc-unable architectures, thus it'll eventually reduce the delta.

The .insn patch has been forwarded to Debian: https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/merge_requests/89

Now the delta is integrated in Debian upload

For jammy I would just backport the kinetic version and name it 1:13.0.1-5~ubuntu22.04.1 or whatever

[Launchpad Janitor (janitor)]

This bug was fixed in the package llvm-toolchain-13 - 1:13.0.1-2ubuntu2.1

---------------
llvm-toolchain-13 (1:13.0.1-2ubuntu2.1) jammy; urgency=medium

  * Backport D115098 for Rust 1.59 (LP: #1973037)
  * d/p/risc/riscv-insn-support.patch: Backport assembler .insn support on riscv64
    for rustc 1.59.0 (LP: #1973041)
