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.

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

llvm-svn: 268253
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:
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.

Checker to validate string constructor parameters.
A common mistake is to swap parameter for the fill-constructor.

Summary:
The check detects multi-statement macros that are used in unbraced conditionals.
Only the first statement will be part of the conditionals and the rest will fall
outside of it and executed unconditionally.

llvm-svn: 266333
Summary: Added the remaining features needed to satisfy C++ Core Guideline Type.6: Always initialize a member variable to cppcoreguidelines-pro-type-member-init. The check now flags all default-constructed uses of record types without user-provided default constructors that would leave their memory in an undefined state. The check suggests value initializing them instead.

Checks if constructors and assignment operators that are marked '= default' are
actually deleted by the compiler.

Differential Revision: http://reviews.llvm.org/D18961
llvm-svn: 266190
Summary:
This check flags initializers of globals that access extern objects, and therefore can lead to order-of-initialization problems (this recommandation is part of CPP core guidelines).
Note that this only checks half of the guideline for now (it does not enforce using constexpr functions).

Summary:
This patch adds the support for detecting suspicious string
literals and their //incorrect// usage.
The following example shows a incorrect character escaping leading
to an embedded NUL character.
```
std::string str = "\0x42"; // Should be "\x42".
```
The patch also add detection of truncated literal when a literal
is passed to a string constructor.

Summary:
Existing checker misc-misplaced-widening-cast was extended:
- New use cases: casted expression as lhs or rhs of a logical comparison or function argument
- New types: beside int, long and long long various char types, short and int128 added
- New option to check implicit casts: forgetting a cast is at least as common and as dangerous as misplacing it. This option can be disabled.
This patch depends on AST Matcher patches D17986 and D18243 and also contains fix for checker misc-bool-pointer-implicit-conversion needed because of the fix in the AST Matcher patch.

Fix for __declspec attributes and const=0 without space
This patch is to address 2 problems I found with Clang-tidy:modernize-use-override.
1: missing spaces on pure function decls.
Orig:
void pure() const=0
Problem:
void pure() constoverride =0
Fixed:
void pure() const override =0
2: This is ms-extension specific, but possibly applies to other attribute types. The override is placed before the attribute which doesn’t work well with declspec as this attribute can be inherited or placed before the method identifier.
Orig:
class __declspec(dllexport) X : public Y
{
void p();
};
Problem:
class override __declspec(dllexport) class X : public Y
{
void p();
};
Fixed:
class __declspec(dllexport) class X : public Y
{
void p() override;
};
