subrkw.d & init_subr_tab_2

[Sam S. <sd...@gn...>]

Hi Bruno,

It appears that the only reason we have subrkw.d in addition to subr.d is:

 --- TURBO-C doesn't get enough memory for compilation!

(comment in spvw.d:init_subr_tab_2).
I tried to enable that code and - lo and behold - it worked!
(Well, after I fixed some bitrot :-).
So, we can get rid of subrkw.d now!
The new code generates a larger run time (by a 0.2%, or 4k)
and a larger memory image (by 0.1%, or 3.5k) though.
This is because subrkw allows subrs to share keyword vectors, thus
eliminating the code to create identical vectors and memory to hold
them.
