  [AMDGPU][NFC] Print the peak pressure across an instruction in downward RP mode

The register pressure printer reports two columns per instruction. In
upward mode, the second one is the tracker's MaxPressure. In downward mode
it was the pressure after the instruction.

Report MaxPressure in both modes. This is NFC today, because the downward
tracker only updates MaxPressure once at the end of advanceToNext(), so
the peak and the pressure after the instruction are the same value.
