r600g: Why all this fiddling with tgsi_helper_copy?

tgsi_helper_copy is used on several occasions to copy a temporary result
into the real destination register to emulate writemasks for OP3 and
reduction operations. According to R600 ISA that's unnecessary.

This patch fixes this use for MAD, CMP and DP4.
