pru: Implement c and n asm operand modifiers
Fix c-c++-common/toplevel-asm-1.c failure for PRU backend, caused by
missing implementation of the "c" asm operand modifier.
gcc/ChangeLog:
* config/pru/pru.cc (pru_print_operand): Implement c and n
inline assembly operand modifiers.
gcc/testsuite/ChangeLog:
* gcc.target/pru/asm-op-modifier.c: New test.
