In this PR we had a write to one vector of a 4-vector tuple.
The vector had mode V1DI, and the target doesn't provide V1DI
moves, so this was converted into:

followed by a DImode move. (The clobber isn't really necessary

Hi,
For code:
```
u64
test_rlwinm_lowpart_mask (u32 v)
{
u32 v1 = ((v << N) | (v >> (32 - N))) & 0xf00;
return (u64)v1;
}
```
We generate "rlwinm 3,3,4,4,23; rldicl 3,3,0,32" instead of "rlwinm 3,3,4,4,23".
Here the "rlwinm" cleans high32 bits already, so "rldicl" is reductant.

Dear all,
the attached trivial patch by Steve fixes a NULL pointer dereference
that occurs when an error shall be emitted for a global entity that
conflicts with a symbol appearing in a COMMON block, but the symbol's
location is not set. This may happen e.g. in the testcase in the PR,

The logical operations for TImode is split after reload pass right now. Some
