Fix a note without a SourceLocation.
#define TEST int y; int x = y;
void foo() {
TEST
}
-Wuninitialized gives this warning:
invalid-loc.cc:4:3: warning: variable 'y' is uninitialized when used here
[-Wuninitialized]
TEST
^~~~
invalid-loc.cc:2:29: note: expanded from macro 'TEST'
#define TEST int y; int x = y;
^
note: initialize the variable 'y' to silence this warning
1 warning generated.
The second note lacks filename, line number, and code snippet. This change
will remove the fixit and only point to variable declaration.
