Subject: radeonsi: Fix VGPR_BIT() definition.
X-Git-Tag: 062012170305~688

radeonsi: Fix VGPR_BIT() definition.

Fixes encoding of VOP3 shader instructions.

The shift was wrong for source registers 2 and 3, and the resulting value was
only 32 bits, so the shift in SICodeEmitter::VOPPostEncode() didn't work as
intended.
