SH4a fortunately offers an instruction to invalidate the
instruction cache, and we use it above, but SH4 doesn't.
However, since the libraries don't contain any nested
functions (the only case in which GCC would emit this pattern)
and we actually emit the ic_invalidate_line_i pattern for
cache invalidation on all SH4 multilibs (even 4-nofpu, that
isn't even corevered here), and pre-SH4 cores don't have
caches, it seems like this code is pointless, unless it's
meant for backward binary compatibility or for userland-only
cache invalidation for say sh4-*-linux-gnu. Such a feature
should probably be moved into a system call, such that the
kernel could do whatever it takes to invalidate a cache line
