[committed] VAX: Fix comment for `*bit<mode>' pattern's peephole

The comment for a peephole provided for the `*bit<mode>' pattern to be 
produced in comparison elimination from a sequence involving a bitwise 
complement operation of one input operand followed by a bitwise AND 
operation between a bitwise complement of said intermediate result and 
the other input operand (which corresponds to a sequence of MCOM and BIC 
machine instructions) incorrectly refers to the first operation as MNEG 
(which is the machine instruction for arithmetic negation) rather than 
MCOM as it is supposed to.  Fix it.

Hi,

 Committed as an obvious trivial inline documentation fix.
