The test to reproduce the RTL instruction.

I see the following invalid mem to mem RTL instruction in test2.c.189r.sched1
when compiling: "test2.c -O2   -mthumb -da -march=armv7-a" with trunk -r174982:

configured with:

--target=arm-linux-gnueabi --enable-__cxa_atexit --disable-nls
--with-float=softfp --with-fpu=vfp --disable-bootstrap
target_alias=arm-linux-gnueabi --enable-languages=c,fortran,lto

(insn 52 50 54 3 (set (mem:HI (plus:SI (reg:SI 167 [ ivtmp.14 ])
                (const_int 2 [0x2])) [5 MEM[base: D.2088_27, offset: 2B]+0 S2
A16])
        (mem:HI (plus:SI (reg:SI 172 [ ivtmp.11 ])
                (const_int 2 [0x2])) [3 MEM[base: D.2087_26, offset: 2B]+0 S2
A16])) test2.c:75 710 {*thumb2_movhi_insn}
     (nil))
