Summary:
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.
Patch produced by
for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done
[This is analogous to LLVM r331272 and CFE r331834]

bugprone-too-small-loop-variable
Summary:
The bugprone-too-small-loop-variable check often catches loop variables which can represent "big enough" values, so we don't actually need to worry about that this variable will overflow in a loop when the code iterates through a container. For example a 32 bit signed integer type's maximum value is 2 147 483 647 and a container's size won't reach this maximum value in most of the cases.
So the idea of this option to allow the user to specify an upper limit (using magnitude bit of the integer type) to filter out those catches which are not interesting for the user, so he/she can focus on the more risky integer incompatibilities.
Next to the option I replaced the term "positive bits" to "magnitude bits" which seems a better naming both in the code and in the name of the new option.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The new checker searches for those for loops which has a loop variable with a "too small" type which means this type can't represent all values which are part of the iteration range.
For example:
```
int main() {
long size = 300000;
for( short int i = 0; i < size; ++i) {}
}
```
The short type leads to infinite loop here because it can't store all values in the `[0..size]` interval. In a real use case, size means a container's size which depends on the user input. Which means for small amount of objects the algorithm works, but with a larger user input the software will freeze.
The idea of the checker comes from the LibreOffice project, where the same check was implemented as a clang compiler plugin, called `LoopVarTooSmall` (LLVM licensed).
The idea is the same behind this check, but the code is different because of the different framework.
