+[AARCH64] STGP instruction is not writing the value of the second register to memory
+Description of problem:
+My application is built with Clang 16 and the option -fsanitize=memtag-stack.
+It means the the MTE protection is activated for the stack.
+The local variables are tagged and the compiler is often using the STGP instruction "Store Allocation Tag and Pair of registers" in order to transfer the value of two 64-bit registers to memory.
+The following instruction was not working as expected:
+   18004: 69000895     	stgp	x21, x2, [x4]
+The value of the second register x2 is not transferred to the memory.
+Only x21 is written.
+
+I think that the issue is in trans_STGP().
+We don't call finalize_memop_pair() like we do for in the general trans_STP().
