  -----------
  [msan][test] Add another target("aarch64.svcount") test case (#164343)

This shows a crash that happens because MSan tries to check the shadow
of a target("aarch64.svcount")-sized argument.

This is the followup to
https://github.com/llvm/llvm-project/pull/164315. This also does a
drive-by fix of those test cases, to remove FileCheck (otherwise, even
if opt passed, the test would still XFAIL because FileCheck cannot find
any CHECK: assertions).

Forked from llvm/test/CodeGen/AArch64/sme2-intrinsics-add.ll
