----------------
Not: these tests can be generalized a bit: `-triple x86_64-linux-gnu` -> `-triple x86_64` (because they work for generic ELF and are not tied to Linux), but there is probably no reason to cause that churn since it has been committed.

----------------
If the intention of `CHECK-NOSANITIZE` is to explicitly check there is no sanitizer variable, it should use some `-NOT:` patterns. However, sanitizer variables should be obvious so that can be omitted.
