[RS6000] lqarx and stqcx. registers

lqarx RT and stqcx. RS are valid only with even numbered gprs.  The
predicate to enforce this happens to allow a loophole, closed by this
patch.

PR target/69548
gcc/
* config/rs6000/predicates.md (quad_int_reg_operand): Don't
allow subregs.
gcc/testsuite/
* gcc.target/powerpc/pr69548.c: New test.
