[PATCH] x86-64: Use push2/pop2 only if the incoming stack is 16-byte aligned

Since push2/pop2 requires 16-byte stack alignment, don't use them if the incoming stack isn't 16-byte aligned. gcc/ PR target/113876 * config/i386/i386.cc (ix86_pro_and_epilogue_can_use_push2pop2): Return false if the incoming stack isn't 16-byte aligned. gcc/testsuite/
