LoongArch: Allow printing symbolic name with "%c" in inline asm

The gcc.dg/ipa/pr122458.c test relies on this.  The doc says "%c" is
for "constant operand" and I think there's no harm to consider symbolic
name a constant operand.

gcc/

	* config/loongarch/loongarch.cc (loongarch_print_operand): Print
	the symbol name for SYMBOL_REF with %c.
