* sh.opt (minline-ic_invalidate): New option.
(musermode): Adjust comment.
* sh.c (sh_initialize_trampoline): Emit library call unless
is set; if it is set, don't emit library call if we can use icbi
instead.
* sh.md (ic_invalidate_line, ic_invalidate_line_sh4a): Also use
icbi for TARGET_SH4_300.
* t-sh (LIB1ASMFUNCS_CACHE): Set.
* doc/invoke.texi: Document -minline-ic_invalidate; Update
-musermode documentation.
