SH4 MMU's memory mapped TLB feature is implemented.SH-Linux seems to write to memory mapped TLB to invalidate a TLB entry,but does not to read it. So only memory write feature is implemented.Work on memory read feature is left....
[sh4] delay slot bug fix
Two bugs about delay slot handlings are fixed.
