[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.
In other words, in a translated instruction array, register status
should not modified before memory access instruction.

[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.
- When a branch instruction is placed at the end of memory segment,
the delay slot is placed at the start of next memory segment.
It means delay slot comes to the start of a translation block.
In such occasion, DELAY_SLOT_CLAREME flag is used to transmit status
between translation blocks. When an exception occurs on this kind of
delay slot, DELAY_SLOT_CLEARME flag cause a status confusion in exception
handling. DELAY_SLOT_CLEARME flag should be cleared on exceptions.
And some items are added to CPU status dump.
