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.

Add a enter/leave record callback so that the offset may be aligned to
the proper value. Otherwise only leaf fields are called, and the first
field needs to be aligned to the outer struct's base alignment while the
last field needs to be aligned to the inner struct's base alignment.
