Summary:
This patch is adding support for conditional expression and overloaded operators.
To decrease false-positive, this patch is adding a list of banned macro names that
has multiple variant with same integer value.
Also fixed support for template instantiation and added an unittest.

Summary:
Arguments can be swapped using fixit when they are not in macros.
This is the same implementation than SwappedArguments. Some code
got lifted to be reused.
Others checks are not safe to be fixed as they tend to be bugs or errors.
It is better to let the user manually review them.

The last check failed as Cla::Cla() was rewritten to Cla::hector().

Summary:
Fixed a crash in cppcoreguidelines-pro-type-member-init when checking record types with indirect fields pre-C++11.
Fixed handling of indirect fields so they are properly checked and suggested fixes are proposed.

This looks for find_all_symbols_db.yaml in all parent directories of the
source file (like we do for compile_commands.json) so we don't have to
pass the path manually.

Summary: Finds return statements in assign operator bodies where the return value is different from '*this'. Only assignment operators with correct return value Class& are checked.

Because modernize-make-shared do almost the same job as
modernize-make-unique, I refactored common code to MakeSmartPtrCheck.

Summary:
This checker finds redundant expression on both side of a binary operator.
The current implementation provide a function to check whether expressions
are equivalent. This implementation is able to recognize the common
subset encounter in C++ program. Side-effects like "x++" are not considered
to be equivalent.
There are many False Positives related to macros and to floating point
computations (detecting NaN). The checker is ignoring these cases.
Example:
```
if( !dst || dst->depth != desired_depth ||
dst->nChannels != desired_num_channels ||
dst_size.width != src_size.width ||
dst_size.height != dst_size.height ) <<--- bug
{
```

Summary:
The checker was noisy when running over llvm code base.
This patch is impriving the way string-compare functions are matched.
1) By default, do not report !strcmp(...) unless it's activate by the user,
2) Only match suspicious expression over a subset of expression (binary operator),
3) Added matching of macro wrapper used with clang on linux.
See bug: 27465.

Summary:
For folds (e.g. std::accumulate), check matches between the provided init value and the range's value_type. A typical error is "std::accumulate(begin, end, 0);", where begin and end have float value_type. See the documentation for more examples.
For now we check std::accumulate, std::reduce and std::inner_product.

Summary:
Checker to validate string constructor parameters.
A common mistake is to swap parameter for the fill-constructor.
```
std::string str('x', 4);
std::string str('4', x);

Summary:
Clang-tidy modernize-raw-string-literal check crashes on run-time assert while it is evaluating compiler predefined identifiers such as
- __FUNCTION__
- __func__
- __PRETTY_FUNCTION__
Check is asserting because it cannot find opening quote for such string literal. It occurs only on debug build config.
I think that it would be good to prune such cases by crossing off predefined expressions - there is no need to evaluate such matches.

Summary: Fixes a crash in cppcoreguidelines-pro-type-member-init when checking some record types with a constructor without a body. We now check to make sure the constructor has a body before looking for missing members and base initializers.
