Fix Neon intrinsic immediate range checking for some double-register operands.
...
Some quad-register intrinsics with lane operands only take a double-register
operand for the vector containing the lane. The valid range of lane numbers
is then half as big as you would expect from the quad-register type.
Note: This currently has no effect because those intrinsics are now handled
entirely in the header file using __builtin_shufflevector, which does its own
range checking, but I want to use this for generating tests.

Add a license comment to the generated arm_neon.h header.

Remove the previous header. I don't think we need to expose to end users
that we use TableGen to produce our version of arm_neon.h, and that header
was also using doubleslash comments which could be a problem when using it
in strict C89 compilations.
