  [AMDGPU][SDAG] Add target-specific ISD::PTRADD combines

This patch adds several (AMDGPU-)target-specific DAG combines for
ISD::PTRADD nodes that reproduce existing similar transforms for
ISD::ADD nodes. There is no functional change intended for the existing
target-specific PTRADD combine.

For SWDEV-516125.
