compiler: new function, clean-file.

This function simplifies cleaning, by allowing a file to
be cleaned to be identified in much the same way as an input
file to load or compile-file.

* autoload.c (compiler_set_entries): The clean-file symbol
is interned and becomes an autoload trigger for the
compiler module.

* stdlib/compiler.tl (clean-file): New function.

* txr.1: Documented.

* stdlib/doc-syms.tl: Updated.
