Auto merge of #60985 - cr1901:msp430-fix, r=alexcrichton

Bump LLVM submodule to fix MSP430 AsmPrinter and assembler syntax mismatch.

Moving on to steps 9 and 10 of the llvm bugfix [guide](https://rust-lang.github.io/rustc-guide/codegen/updating-llvm.html#bugfix-updates), now that Rust's copy of LLVM was [updated](https://github.com/rust-lang/llvm-project/pull/13).

This PR closes issue #59077. Nightlies following this PR should have working msp430 codegen again :D.

Thanks for the prompt response even though it took me a while to get this "simple" PR done!
