[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....

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....

cpu_get_phys_page_debug should return target_phys_addr_t
instead of target_ulong to be consistent.
