target/mips: Mark switch fallthroughs with interpretable comments

Mark switch fallthroughs with comments, in cases fallthroughs
are intentional.

The comments "/* fall through */" are interpreted by compilers and
other tools, and they will not issue warnings in such cases. For gcc,
the warning is turnend on by -Wimplicit-fallthrough. With this patch,
there will be no such warnings in target/mips directory. If such
warning appears in future, it should be checked if it is intentional,
and, if yes, marked with a comment similar to those from this patch.

The comment must be just before next "case", otherwise gcc won't
understand it.
