Hi, The terminology in armv8 is advsimd rather than neon.  Can we
rename neon-intrinsics to advsimd-intrinsics or simd-intrinsics
throughout please.  The existing gcc.target/aarch64/simd directory of
tests will presumably be superseded by this more comprehensive set of
tests so I suggest these tests go in gcc.target/aarch64/advsimd and we
eventually remove gcc.target/aarch64/simd/ directory.

GNU style should apply throughout this patch series, notably double
space after period in comments and README text.  Space before left
parenthesis in function/macro call and function declaration.  The
function name in a declaration goes on a new line.  The GCC wiki notes
on test case state individual test should have file names ending in
_<number>, see here https://gcc.gnu.org/wiki/TestCaseWriting

I'm OK with the execute only no scan nature of the tests.

Neon -> Advanced SIMD as below.

Upper case the macro's rather than camel case.
