tcg: Add support for vector bitwise select
This operation performs d = (b & a) | (c & ~a), and is present
on a majority of host vector units. Include gvec expanders.

tcg: Add gvec expanders for vector shift by scalar
Allow expansion either via shift by scalar or by replicating
the scalar for shift by vector.

tcg: Add gvec expanders for variable shift
The gvec expanders perform a modulo on the shift count. If the target
requires alternate behaviour, then it cannot use the generic gvec
expanders anyway, and will have to have its own custom code.

tcg: Specify optional vector requirements with a list
Replace the single opcode in .opc with a null-terminated
array in .opt_opc. We still require that all opcodes be
used with the same .vece.

Validate the contents of this list with CONFIG_DEBUG_TCG.
All tcg_gen_*_vec functions will check any list active
during .fniv expansion. Swap the active list in and out
as we expand other opcodes, or take control away from the
front-end function.

Convert all existing vector aware front ends.

tcg: Implement tcg_gen_gvec_3i()
Let's add tcg_gen_gvec_3i(), similar to tcg_gen_gvec_2i(), however
without introducing "gen_helper_gvec_3i *fnoi", as it isn't needed
for now.

tcg: Fix LGPL version number
It's either "GNU *Library* General Public version 2" or "GNU Lesser
General Public version *2.1*", but there was no "version 2.0" of the
"Lesser" library. So assume that version 2.1 is meant here.

tcg: Add generic vector helpers with a scalar operand
Use dup to convert a non-constant scalar to a third vector.

Add addition, multiplication, and logical operations with an immediate.
Add addition, subtraction, multiplication, and logical operations with
a non-constant scalar. Allow for the front-end to build operations in
which the scalar operand comes first.

tcg: Add generic helpers for saturating arithmetic
No vector ops as yet. SSE only has direct support for 8- and 16-bit
saturation; handling 32- and 64-bit saturation is much more expensive.

tcg: Add generic vector ops for constant shifts
Opcodes are added for scalar and vector shifts, but considering the
varied semantics of these do not expose them to the front ends. Do
go ahead and provide them in case they are needed for backend expansion.
