Note that in the general reg=reg,reg case we're restricted
to 16-bit insertions. This makes it easy to allow "any"
constant as input, as post-truncation it will fit into the
constant load insn for which we have room in the bundle.

Remove suboptimal register shifting in qemu_ld/st ops, introduced at the
CONFIG_TCG_PASS_AREG0 time.
As mem_idx is now loaded in register R58/R59 for the slow path, we have
to make sure to do it last, to not add additional register constraints.

Instead of embedding knowledge of the memory and I/O address spaces in the
memory core, maintain a list of all address spaces. This list will later
be extended dynamically for other bus masters.

AddressSpace contains a member, current_map, of type FlatView. Since we
want to limit the leakage of internal types to public headers, switch to
a pointer to a FlatView. There is no performance impact as this isn't used
during lookups, only address space reconfigurations.

Using an unfiltered memory listener will cause regions to be reported

filtering to fix this.

exec-obsolete.h used to hold pre-memory-API functions that were used from
device code prior to the transition to the memory API. Now that the
transition is complete, the name no longer describes the file. The
functions still need to be merged better into the memory core, but there's
no danger of anyone using them.
