[committed] pru: Use unsigned constants for register classes

[Dimitar Dimitrov]

Fix the following warning:

  .../gcc/gcc/config/pru/pru.h:249:43: warning: narrowing conversion of ‘-1’ 
from ‘int’ to ‘unsigned int’ [-Wnarrowing]
    249 |     /* ALL_REGS       */ { ~0,~0, ~0, ~0, ~0}                   \

Pushed to trunk as r16-5124-gc6fce499ba17f3.

gcc/ChangeLog:

        * config/pru/pru.h (REG_CLASS_CONTENTS): Use unsigned integer
        constants.
