Use __attribute__((fallthrough)) rather than magic GCC comments.
GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that. Clang recently added
the same thing.
GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments. Clang, however,
only seems to like "__attribute__((fallthrough))". Fortunately, GCC
accepts that too.
A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.
This is an automated commit, made with the following perl one-liner:
#!/usr/bin/perl -i -p
s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;
