(llvm) No highlighting for block (C-style) comments

[eisenwave]

Describe the issue

C-style comments don't get highlighted in LLVM IR.

Which language seems to have the issue?

LLVM IR.

Are you using highlight or highlightAuto?

highlight

Sample Code to Reproduce

/* ... */

Expected behavior

This should be highlighted as a C-style comment.

Additional context

https://llvm.org/docs/LangRef.html#identifiers

Comments are delimited with a ‘;’ and go until the end of line. Alternatively, comments can start with /* and terminate with */.

To my knowledge, C-style comments are a fairly recent feature (2025), so it's unsurprising that this isn't supported yet.
