AMDGPU: Extract full 64-bit subregister and use subregs
Instead of extracting both 32-bit components from the 128-bit
register. This produces fewer copies and is easier for
the copy peephole optimizer to understand and see the actual uses
as extracts from a reg_sequence.
This avoids needing to handle subregister composing in the
PeepholeOptimizer's ValueTracker for this case.
