Log Message:
-----------
tcg/i386: Support INDEX_op_dup2_vec for -m32
Unknown why -m32 was passing with gcc but not clang; it should have
failed for both. This would be used for tcg_gen_dup_i64_vec, and
visible with the right TB and an aarch64 guest.

Changed paths:
M tcg/tcg-op-gvec.c
Log Message:
-----------
tcg: Add choose_vector_size
This unifies 5 copies of checks for supported vector size,
and in the process fixes a missing check in tcg_gen_gvec_2s.
This lead to an assertion failure for 64-bit vector multiply,
which is not available in the AVX instruction set.
