Fixed opcodes for DS_WRITE_SRC2_B32 and DS_WRITE_SRC2_B64.
I found bug in the AMD SI ISA Reference Guide: DS_WRITE_SRC2_B32 and
DS_WRITE_SRC2_B64 have wrong opcodes (DS_WRITE_SRC2_B32=140,
DS_WRITE_SRC2_B64=204). These opcodes causes GPU's hang up (verified for
DS_WRITE_SRC2_B64).
Correct opcodes (verified by me) are DS_WRITE_SRC2_B32=141 (0x8d) and
DS_WRITE_SRC2_B64=205 (0xcd).
In the attachments is patch that fix that bug.</pre>
