LOOP named NIL does not establish a BLOCK

Description

(loop named nil do (return 1)) does not establish a block at all instead of one named NIL, as I'd expect from 6.1.1.5.6: "The loop named construct gives a name for the block of the loop". There's no mention that specifying the name as NIL instead of defaulting to NIL through omission allows for the omission of the loop block.

(In [15924]) Fix the loop facility so that (loop named nil ...) actually generates a block named nil.

A CL loop form can have only one named clause, so in loop-do-named, simply set *loop-names* to a list containing the symbol that should be the loop's name.

In loop-translate, we know that *loop-names* will be either nil or a list of one symbol, so just use (car *loop-names*) as the name of the loop's implicit block.

Closes ticket:1099.
