Committed, MMIX: Fix gcc.c-torture/compile/labels-3.c

[Hans-Peter Nilsson <hp at bitrange dot com>]

This fixes gcc.c-torture/compile/labels-3.c.  For that test,
there's an incoming (minus:HI (subreg:HI (label_ref:DI 0) 6)
(subreg:HI (label_ref:DI 0) 6)), not the usual CONST_INT.  I
also spotted a typo; that mmix_output_octa call should have 1 as
its last parameter to get a mnemonic output.  Apparently it's
not called anymore, and thinking about it, there's no reason it
would be called.  Better put a prominent watch on it with an
abort ().

	* config/mmix/mmix.c (mmix_assemble_integer) <case 1, 2>: Handle
	non-CONST_INT through default_assemble_integer.
	<case 4>: Likewise, for non-CONST_INT, non-SYMBOL_REF.
	<case 8>: Abort for CONST_DOUBLE.
