d997143533 tcg: Make DisasContextBase.tb const
There is nothing within the translators that ought to be
changing the TranslationBlock data, so make it const.

This does not actually use the read-only copy of the
data structure that exists within the rx region.

a66424ba17 tcg: Add tcg_gen_bswap_tl alias
The alias is intended to indicate that the bswap is for the
entire target_long.  This should avoid ifdefs on some targets.

23850a74af tcg: Implement gvec support for rotate by scalar
No host backend support yet, but the interfaces for rotls
are in place.  Only implement left-rotate for now, as the
only known use of vector rotate by scalar is s390x, so any
right-rotate would be unused and untestable.

v3: Drop the generic expansion from rot to shift; we can do better
    for each backend, and then this code becomes unused.

b0f7e7444c tcg: Implement gvec support for rotate by immediate
No host backend support yet, but the interfaces for rotli
are in place.  Canonicalize immediate rotate to the left,
based on a survey of architectures, but provide both left
and right shift interfaces to the translators.

07dada0336 tcg: Fix integral argument type to tcg_gen_rot[rl]i_i{32,64}
For the benefit of compatibility of function pointer types,
we have standardized on int32_t and int64_t as the integral
argument to tcg expanders.

We converted most of them in 474b2e8f0f, but missed the rotates.
