Replace TARGET_WORDS_BIGENDIAN
...
Convert the TARGET_WORDS_BIGENDIAN macro, similarly to what was done
with HOST_BIG_ENDIAN. The new TARGET_BIG_ENDIAN macro is either 0 or 1,
and thus should always be defined to prevent misuse.

Replace config-time define HOST_WORDS_BIGENDIAN
...
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.
This can help to make some code independent from qemu too.
gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

tcg: Expand MO_SIZE to 3 bits
...
We have lacked expressive support for memory sizes larger
than 64-bits for a while. Fixing that requires adjustment
to several points where we used this for array indexing,
and two places that develop -Wswitch warnings after the change.

Introduce no-op size_memop to aid preparatory conversion of
interfaces.
Once interfaces are converted, size_memop will be implemented to
return a MemOp from size in bytes.
