[CIR][CIRGen][Builtin][Neon] Lower neon_vaesmcq_u8 (llvm#1072)

The test case is from
[clang/test/CodeGen/neon-crypto.c](https://github.com/llvm/clangir/blob/dbf320e5c3db0410566ae561067c595308870bad/clang/test/CodeGen/neon-crypto.c#L28)
Need a dedicated test file as RunOptions has crypto related target
features.
