Fixed PR13938: the ARM backend was crashing because it couldn't select a VDUPLANE node with the vector input size different from the output size. This was bacause the BUILD_VECTOR lowering code didn't check that the size of the input vector was correct for using VDUPLANE.

Improve codegen for BUILD_VECTORs on ARM.
...
If we have a BUILD_VECTOR that is mostly a constant splat, it is often better to splat that constant then insertelement the non-constant lanes instead of insertelementing every lane from an undef base.

ARM VLDR/VSTR instructions don't need a size suffix.
...
Canonicallize on the non-suffixed form, but continue to accept assembly that
has any correctly sized type suffix.
