2018-02-08	tcg: Add generic vector helpers with a scalar operand	Richard Henderson	1	-1/+58
	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.

2018-02-08	tcg: Add generic helpers for saturating arithmetic	Richard Henderson	1	-0/+10
	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. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2018-02-08	tcg: Add generic vector ops for constant shifts	Richard Henderson	1	-0/+35
	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. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
