  Log Message:
  -----------
  [AMDGPU][SDAG] Enable ISD::PTRADD for 64-bit AS by default

Also removes the command line option to control this feature.

There seem to be mainly two kinds of test changes:
- Some operands of addition instructions are swapped; that is to be expected
  since PTRADD is not commutative.
- Improvements in code generation, probably because the legacy lowering enabled
  some transformations that were sometimes harmful.

For SWDEV-516125.
