Subject: screwy opcodes in 'as' overlooked (#71)
Index:	bin/as/{as12,as14,as17,as22,as27}.s 2.11BSD

Description:
	When several of the obsolete/deprecated/oddball opcodes were
	removed from the assembler the usage of these in the assembler
	itself was overlooked (the compiler never generates them).

Repeat-By:
	Attempt to assemble the assembler.  Note the errors on
	'dvd', 'mpy' and 'als'.  Changing these to 'div', 'mul' and 'ash'
	fixes the problem.

Fix:
	Apply the patch below and reinstall the assembler.   Both the old
	and new assemblers recognize the "standard" opcodes, there wasn't
	any risk of the assembler not being able to reconstitute itself.
