We use nir_ssa_defs for nir_builder args, so this takes a nir_src and
makes one so it can be passed in.

So far we'd only used nir_builder to build brand new programs. But if
we're doing modifications to instructions (like in a lowering pass), then
we want to generate new stuff before the instruction we're modifying.

These will be useful for prog->nir and tgsi->nir.
v2: Don't forget to mark nir_swizzle as inline (Eric).

Both prog->nir and tgsi->nir will want to use these.

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.
