Remove unnecessary NYIs in Decompose

GT_DIV, GT_MOD, GT_UDIV, GT_ROL, GT_ROR, and GT_MULHI will never make it
to decompose, so remove the case statements for those operations. They
will fall through to the default case, which noway_asserts that we haven't
gotten to decompose with an oper that we don't recognize.
