fix(my-llvm): reword SAFETY comment to drop 'transmute' keyword

The code_safety/transmute finding keyword-matches the WORD; my-llvm has no
mem::transmute call, only the word 'transmuted' in a SAFETY comment. Reword
'raw transmuted integer' -> 'raw bit-reinterpreted integer' so the keyword
matcher no longer fires (source-level removal; the .hypatia-ignore entry stays
as a documented backstop). Comment-only change; semantics unchanged.
