Subject: [PATCH] [clang-tidy] readability-container-contains literal suffixes
Before this PR, readability-container-contains fixits did not handle
integer literal suffixes correctly. It e.g. changed
```
MyMap.count(2) != 0U;
```
into
```
MyMap.contains(2)U;
```
With this PR, it correctly changes it to
```
MyMap.contains(2);
```
