sh4: fix tas.b @Rn instruction

(Shin-ichiro KAWASAKI, based on a patch from Andrzej Zaborowski)

[sh4] code translation bug fix

When a TLB miss occurs while pre-decrement store instruction such as
"mov.l Rm, @-Rn" is executed, re-execution of such instruction cause
status confusion. Because pre Rn decrement is executed before TLB miss,
re-execution decrements Rn again....

[sh4] MMU bug fix

Some bugs on SH4 MMU are fixed.

- When a TLB entry is overwritten or invalidated, tlb_flush_page() should be
invoked to invalidate old entry.
- When a ASID is changed, tlb_flush() should be invoke to invalidate entries
which have old ASID....

[sh4] memory mapped TLB entries

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.

- After an exception occurred in delay slot, the branch instruction
before delay slot should be executed again. To judge such re-execution
is necessery or not, delay slot status is kept in SH4 CPU data structure....
