Due to a copy-paste error in tb_invalidate_phys_range, the wrong
start address was passed to tb_invalidate_phys_page_range__locked.
Correct is to use the start of each page in turn.

For the most part we can use the new generic routine,
though exceptions need some post-processing to sort
invalid from integer overflow.

When we generate code for guest loads and stores, at the moment they
end up being requests for a host-endian access. So for target-system-nios2
(little endian) a load like
   ldw        r3,0(r4)
results on an x86 host in the TCG IR
   qemu_ld_a32_i32 r3,loc2,al+leul,0
but on s390 it is
   qemu_ld_a32_i32 r3,loc2,al+beul,0

The result is that guests don't work on big-endian hosts.

Use the MO_TE* memops rather than the plain ones.

There is an overflow problem in mmap_find_vma_reserved:
when reserved_va == UINT32_MAX, end may overflow to 0.
Rather than a larger rewrite at this time, simply avoid
the final byte of the VA, which avoids searching the
final page, which avoids the overflow.
