Advice needed: programmatically generating primops?

[Geoffrey Mainland]

Hi All,

There is a huge amount of boilerplate involved in adding a full
complement of vector primops to GHC. I would like to reduce this
boilerplate by programmatically generating the vector primops. My plan
is to add utils/genvecprimops and #include its output into
primops.txt.pp.

Does this sound reasonable? Any objections? While I'm at it, is there
any related cleanup I could undertake?

Thanks,
Geoff
