  Log Message:
  -----------
  tlb: Add "ifetch" argument to cpu_mmu_index()

This is set to true when the index is for an instruction fetch
translation.

The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS
acessors.

All targets ignore it for now, and all other callers pass "false".

This will allow targets who wish to split the mmu index between
instruction and data accesses to do so. A subsequent patch will
do just that for PowerPC.

  softmmu: add helper function to pass through retaddr

This patch introduces several helpers to pass return address
which points to the TB. Correct return address allows correct
restoring of the guest PC and icount. These functions should be used when
helpers embedded into TB invoke memory operations.

  softmmu: remove now unused functions

Now that the cpu_ld/st_* function directly call helper_ret_ld/st, we can
drop the old helper_ld/st functions.

  cpu-exec: introduce loop exit with restore function

This patch introduces loop exit function, which also
restores guest CPU state according to the value of host
program counter.
