Silviu Baranga b14097000b 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.

James Molloy 49bdbce8e1 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.

Jim Grosbach 3e2c6f380c 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.

Rafael Espindola 29dda21e96 Remove arm_apcscc from the test files. It is the default and doing this 
matches what llvm-gcc and clang now produce.

Bob Wilson 2e076c4e02 Add support for ARM's Advanced SIMD (NEON) instruction set. 
This is still a work in progress but most of the NEON instruction set
is supported.
