  -----------
  AMDGPU: Add test for 16 bit unsigned scratch offsets (#110255)

Large scratch offset with one on highest bit selected as negative,
negative offset has same binary representation in 16 bits as large
unsigned offset.

(cherry picked from commit e9d12a6b451bd403d95105aa976a011dc821f126)

  Log Message:
  -----------
  AMDGPU: Fix inst-selection of large scratch offsets with sgpr base (#110256)

Use i32 for offset instead of i16, this way it does not get interpreted
as negative 16 bit offset.
