  tcg/aarch64: Do not advertise minmax for MO_64 (2019-05-13 22:52:08 +0000)

----------------------------------------------------------------
Improve code generation for vector duplication.
Add vector expansions for shifts by non-constant scalar.
Add vector expansions for shifts by vector.
Add integer and vector expansions for absolute value.
Several patches in preparation for Altivec.
Bug fix for tcg/aarch64 vs min/max.
