clang-tidy produces a `readability-simplify-boolean-expr` warning to simplify expressions with macros using DeMorgan's theorem despite `readability-simplify-boolean-expr.IgnoreMacros` being set to `true`.
Simplified test case:
```
#define is_a_favorite_number(_i) (_i == 42 || _i == 3 || _i == 1000000)
bool UseNumber(int i) { return i >= 0 && !is_a_favorite_number(i); }
```
.clang-tidy config:
```
---
Checks:
'-*,
readability-simplify-boolean-expr
'
CheckOptions:
- key: readability-simplify-boolean-expr.IgnoreMacros
value: true
```
Produces the following:
```
1 warning generated.
test_bool_simplification.cpp:4:42: error: boolean _expression_ can be simplified by DeMorgan's theorem [readability-simplify-boolean-expr,-warnings-as-errors]
4 | bool UseNumber(int i) { return i >= 0 && !is_a_favorite_number(i); }
