[Bug translator/2140] New: 'delete' operator doesn't work on all variations

see http://sourceware.org/ml/systemtap/2006-q1/msg00051.html

Presently, use of the 'delete' operator does not generate valid code for all
possible variations.  It is agreed that 'delete' should work on indices of maps
or on the entire map, whether the map value-type is string, integer, or stat. 
It should probably also work as a reset for scalar stat variables as well, since
there's no other way to clear them.

It's debatable whether 'delete' should act as a reset for scalar strings and
integers, but since no-one seems to have a strong opinion against this, we
should probably add it for consistency.

See src/testsuite/buildok/delete.stp for a testcase which currently fails.
