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.
