aurel32 3bf73a4980 SH4: use uint32_t/i32 based types/ops 
Use uint32_t/i32 based types/ops to stay consistent with previous dyngen
code. Thanks to Paul Brook for noticing that.

aurel32 825c69ce02 sh4: fix tas.b @Rn instruction 
(Shin-ichiro KAWASAKI, based on a patch from Andrzej Zaborowski)

aurel32 7da76bcef2 [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.

aurel32 06afe2c884 [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.
- The check for shared bit in TLB entry causes multiple TLB hit exception.
  As SH3's MMU, shared bit is ignored.
- ASID is used when MMUCR's SV bit or SR's MD bit is zero.
  No need to check both bits are zero.

aurel32 29e179bc3f [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.

aurel32 274a9e70de [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.

j_mayer 6ebbf39000 Replace is_user variable with mmu_idx in softmmu core, 
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
