Etienne Bergeron c87599f480 [clang-tidy] Improve misc-redundant-expression and decrease false-positive
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.

Etienne Bergeron e646a833ab [clang-tidy] Add FixIt for swapping arguments in string-constructor-checker.
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.

Etienne Bergeron bda187decd [clang-tidy] New checker for redundant expressions.
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
    {

Etienne Bergeron 1b94f6504b [clang-tidy] Enhance misc-suspicious-string-compare to move down false-positives.
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.

Alexander Kornienko 6e2f32c561 A clang-tidy check for std:accumulate.
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.

Etienne Bergeron bae829ede5 [clang-tidy] Add new checker for comparison with runtime string functions.
Summary:
This checker is validating suspicious usage of string compare functions.

Example:
```
  if (strcmp(...))       // Implicitly compare to zero
  if (!strcmp(...))      // Won't warn
  if (strcmp(...) != 0)  // Won't warn
```

This patch was checked over large amount of code.
There is three checks:
  [*] Implicit comparator to zero (coding-style, many warnings found),
  [*] Suspicious implicit cast to non-integral (bugs!?, almost none found),
  [*] Comparison to suspicious constant (bugs!?, found two cases),

Example:
[[https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c |
https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c]]

```
      else if(strcmp(id, "select") == 0)
      {
         array->array[i].key1 = 25;
      }
      else if(strcmp(id, "sk") == 28)      // BUG!?
      {
         array->array[i].key1 = 20;
      }

Alexander Kornienko bfb43b7298 [Clang-tidy] Fix for crash in modernize-raw-string-literal check
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.
