Unify comment styles across MJIT sources

I'm writing `//` comments in newer MJIT code after C99 enablement
(because I write 1-line comments more often than multi-line comments
 and `//` requires fewer chars on 1-line) and then they are mixed
with `/* */` now.

For consistency and to avoid the conversion in future changes, let me
finish the rewrite in MJIT-related code.
