[Clang] UCN in preprocessor-pasted identifier not resolved to unicode

With the snippet:
```
#define CAT(a,b) a##b
char foo\u00b5;
char*p = &CAT(foo, \u00b5);
```
Clang resolves the variable name as `"fooµ"`, and the concatenated reference to it next line as `"foo\u00b5"`, then error on undeclared reference. Other implementations instead treat both the same: https://godbolt.org/z/M1fejPK36
Wasn't encountered in real world, just a what-if test I came up for my implementation.
