radeon/llvm: Add special nodes for SALU operations on VCC
The VCC register is tricky because the SALU views it as 64-bit, but the
VALU views it as 1-bit. In order to deal with this we've added some
special bitcast and binary operations to help convert from the 64-bit
SALU view to the 1-bit VALU view and vice versa.
