Compsc1

[: +./ < Improved

The following dyads are now supported by special code for
Boolean, integer, floating point, literal, or symbol vectors or scalars:

	[: +./ comp		+./@:comp
	[: *./ comp		*./@:comp
	[: I.  comp		I.@:comp

where comp is one of = ~: < <: >: > E.
(< <: >: > not available for literal).
These are similar to the
special code for comp i. 1: etc. for J5.02.



Time and space savings depend on the arguments used.
For example:

   ts=: 6!:2 , 7!:2@]   NB. time and space
   x=: ?1e6$1e9
   y=: 1.5e9
   ts '+./x>y'
0.0322982 1.04973e6
   ts 'x ([: +./ >) y'  NB. scan entire x
0.0181442 1408
   ts '*./x>y'
0.0246665 1.04973e6
   ts 'x ([: *./ >) y'  NB. immediate hit
