Userspace ARM BE8 support
Add support for ARM BE8 userspace binaries.
i.e. big-endian data and little-endian code.
In principle LE8 mode is also possible, but AFAIK has never actually
been implemented/used.
System emulation doesn't have any useable big-endian board models,
but should in principle work once you fix that.
Dynamic endianness switching requires messing with data accesses,
preferably with TCG cooperation, and is orthogonal to BE8 support.

[PMM: various changes, mostly as per my suggestions in code review:
* rebase
* use EF_ defines rather than hardcoded constants
* make bswap_code a bool for future VMSTATE macro compatibility
* update comment in cpu.h about TB flags bit field usage
* factor out load-code-and-swap into arm_ld*_code functions and
get_user_code* macros
* fix stray trailing space at end of line
* added braces in disas.c to satisfy checkpatch
