	In util/getroot and efidisk slightly modify exitsing comment to mostly retain it but still make GCC7 compliant with respect to fall through annotation. In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as upstream. In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to suppress GCC7 warning. In grub-core/gnulib/regexec.c use new __attribute__, because existing annotation is not recognized by GCC7 parser (which requires that comment immediately precedes case statement). Otherwise add FALLTHROUGH comment. Closes: 50598
