nir: Add an ALU op builder kind of like ir_builder.h

v2: Rebase on the nir_opcodes.h python code generation support.
v3: Use SSA values, and set an appropriate writemask on dot products.
v4: Make the arguments be SSA references as well.  This lets you stack up
    expressions in the arguments of other expressions, at the cost of
    having to insert a fmov/imov if you want to swizzle.  Also, add
    the generated file to NIR_GENERATED_FILES.
v5: Use more pythonish style for iterating the list.
v6: Infer the size of the dest from the size of the srcs, and auto-swizzle
    a single small src out to the appropriate size.
v7: Add little helpers for initializing the struct, add a typedef for the
    struct like other nir types have.
