The patch adjusts the existing `llvm::DenseMap<unsigned, T>` and
`llvm::DenseSet<unsigned>` objects that store source locations, so
that they use `SourceLocation` directly instead of `unsigned`.
This patch relies on the `DenseMapInfo` trait added in D89719.
It also replaces the construction of `SourceLocation` objects from
the constants -1 and -2 with calls to the trait's methods `getEmptyKey`
and `getTombstoneKey` where appropriate.

Prevent fixes being displayed if usages are found in the scratch buffer.
See [[ https://bugs.llvm.org/show_bug.cgi?id=46219 | Fix-It hints are being generated in the ScratchBuffer ]].
It may be wise down the line to put in a general fix in clang-tidy to prevent ScratchBuffer replacements being applied, but for now this will help.

This changes the behavious of `RenamerClangTidyCheck` based checks by grouping declarations of the same thing into 1 warning where it is first declared.
This cleans up clang-tidy output and prevents issues where 1 fix-it couldn't be applied, yet all other warnings(and fix-its) for the same declaration would be applied.
The old behaviour of forward declaring a class without defining it isn't affected, i.e. no warnings will be emitted for that case.

Summary:
Sometimes in templated code Member references are reported as `DependentScopeMemberExpr` because that's what the standard dictates, however in many trivial cases it is easy to resolve the reference to its actual Member.
Take this code:
```
template<typename T>
class A{
int value;
A& operator=(const A& Other){
value = Other.value;
this->value = Other.value;
return *this;
}
};
```
When ran with `clang-tidy file.cpp -checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.MemberPrefix, value: m_}]}" -fix`
Current behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.value;
this->value = Other.value;
return *this;
}
};
```
As `this->value` and `Other.value` are Dependent they are ignored when creating the fix-its, however this can easily be resolved.
Proposed behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.m_value;
this->m_value = Other.m_value;
return *this;
}
};
```

Summary:
Typically most main functions have the signature:
```
int main(int argc, char *argv[])
```
To stick with convention when renaming parameters we should ignore the `argc` and `argv` names even if the parameter style says they should be renamed. This patch addresses this by checking all ParmVarDecls if they form part of a function with a signature that matches main `int name(int argc, char * argv[], (optional char *env[]))`

Before this patch, readability-identifier-naming contained a significant amount
of logic for (a) checking the style of identifiers, followed by (b) renaming/
applying fix-its. This patch factors out (b) into a separate base class so that
it can be reused by other checks that want to do renaming. This also cleans up
readability-identifier-naming significantly, since now it only needs to be
concerned with the interesting details of (a).
