report message for operator %a on unaddressible operand

Hi,

For PR96866, when printing asm code for modifier "%a", an addressable
operand is required.  While the constraint "X" allow any kind of
operand even which is hard to get the address directly. e.g. extern
symbol whose address is in TOC.
An error message would be reported to indicate the invalid asm operand.

Compare with previous version, test case is updated with -mno-pcrel.

Bootstrap&regtest pass on ppc64{,le}.
Is this ok for trunk?

BR,
