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.
