  Log Message:
  -----------
  [HIP] Warn capture this pointer in device lambda

HIP currently diagnose capture of this pointer in device lambda in
host member functions. If this pointer points to managed memory,
it can be used in both device and host functions. Under this
situation, capturing this pointer in device lambda functions
in host member functions is valid usage. Change the diagnostic
about capturing this pointer to warning.
