Add llvm-mir highlighting (#1398)

* Add injection regex for more languages

To support embedding them in other languages like markdown.

* Add llvm-mir highlighting

LLVM Machine IR is dumped as yaml files that can embed LLVM IR and
Machine IR.

To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.

* Update submodule with fixed multiline comments
