Committed, MMIX: Don't check for SYMBOL_REF for 4-bytes in mmix_assemble_integer

[Hans-Peter Nilsson]

To avoid giving the impression that symbolic expressions are
well-handled by "TETRA expression" (only "pure numbers", thank
you), I made this tweak.  Tested by putting:

	if (GET_CODE (x) == SYMBOL_REF)
	  abort ();

before the changed line and running the testsuite on that.
Apparently SYMBOL_REF:s don't get there.  This is expected,
since this is a 64-bit arch.

	* config/mmix/mmix.c (mmix_assemble_integer) <case 4>: Don't
	handle SYMBOL_REF.
