[committed] clarify sleu_operand

[Eric Christopher]

While looking into changes for LE_EXPR vs LT_EXPR coming from the front
end I decided that this code was easier to look at done this way.
Ideally what we'll want is to do the checks in mips_emit_scc and be able
to support the full range of the slt operand for LE. However, for now...

No regressions. Committed to mainline.

	* config/mips/predicates.md (sleu_operand): Use
	IN_RANGE to specify range of operand.
