This is checking things like
```
//expected-note@+1 {{previous declaration is here}}
void __attribute__((target_version("bti+flagm2"))) one(void) {}
//expected-error@+1 {{multiversioned function redeclarations require identical
target attributes}}
void __attribute__((target_version("flagm2+bti"))) one(void) {}
```
(example taken from clang/test/Sema/attr-target-version.c)
At this point we know that the new declaration is triggering multiversioning
therefore the old was the (implicit or explicit) default.
