Cleanup number primop conversion names

Don't use "extend" or "narrow" in some of the user-facing primops
names for conversions.

  - Names like `narrowInt32#` are misleading when `Int` is 32-bits.

  - Names like `extendInt64#` are flat-out wrong when `Int is
    32-bits.

  - `narrow{Int,Word}<N>#` however map a type to itself, and so don't
    suffer from this problem. They are left as-is.
