Go to definition not working properly with cross-file redefined macros

[xarkes]

Observed behavior

• .ccls:

  clang

• test.cc:

  
  #include "other.h"

undef LOG

define LOG(args) fprintf(stderr, args)

int main() { LOG("Log\n"); return 0; }

* `other.h`
```cpp
#include <stdio.h>
#define LOG(args) fprintf(stdout, "Other: " args);

Expected behavior

When using LSP "go to definition" on the LOG macro use inside the main() function I would expect my cursor to jump to the definition in test.cc. Otherwise my client either lists every definition, or worse, jumps to the first one it wants. This is not right as there is clearly no doubt about which macro is being in use from the compiler point of view.

Note: Maybe similar to https://github.com/MaskRay/ccls/issues/885

Steps to reproduce

1. Create a new project with the provided files above
2. Use your LSP client and try "go to definition" on the LOG
