Well, currently tests in gcc.target/arm/neon serve no functional / 
correctness purpose. The only thing they check is if the correct 
instruction is generated at O0 which is probably enough for that case.

I would rather that we put in scan-assembler tests in your testsuite 
rather than anything else.
