r600g: fix tgsi_op2_s with trans-only instructions
This fixes the issue when dst and src is the same reg and operation on one
channel overwrites the source for other channels, e.g.:
UMUL TEMP[2].xyz, TEMP[0].xyzz, TEMP[2].xxxx
In this example the result of the operation on channel x is written in
TEMP[2].x and then used as a second source operand for channels y and z
instead of original value in TEMP[2].x.
This patch stores the results in temp reg and moves them to
dst after performing operation on all channels.
