    Fix PR 93242: patchable-function-entry broken on MIPS
    
    On MIPS, .set noreorder/reorder needs to emitted around
    the nop.  The template for the nop instruction uses %(/%) to
    do that.  But default_print_patchable_function_entry uses
    fprintf rather than output_asm_insn to output the instruction.
    
    This fixes the problem by using output_asm_insn to emit the nop
    instruction.
    
    ChangeLog:
    
    PR middle-end/93242
    * targhooks.c (default_print_patchable_function_entry): Use
    output_asm_insn to emit the nop instruction.
