2.26.137: API cleanup in preparation for release

Rename RUN-PROGRAM/ to RUN-PROGRAM.
Can't export it from ASDF because it causes a clash in SB-GROVEL.

Rename SUB-OBJECT and :PATH to ACCESS-AT and :AT.

Get rid of TRANSLATE-OUTPUT-P.
Instead, check whether the component's BUILD-OPERATION
is the same as the current operation.
