Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Adrian Prantl 9fc8faf9e6 Remove \brief commands from doxygen comments.
This is similar to the LLVM change https://reviews.llvm.org/D46290.

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
for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done

Justin Lebar 9091055efa Move UTF functions into namespace llvm.
Summary:
This lets people link against LLVM and their own version of the UTF
library.

I determined this only affects llvm, clang, lld, and lldb by running

$ git grep -wl 'UTF[0-9]\+\|\bConvertUTF\bisLegalUTF\|getNumBytesFor' | cut -f 1 -d '/' | sort | uniq
  clang
  lld
  lldb
  llvm

Tested with

  ninja lldb
  ninja check-clang check-llvm check-lld

(ninja check-lldb doesn't complete for me with or without this patch.)

Alexander Kornienko ebb43caae2 Handle zero-width and double-width characters in string literals and comments.
Summary:
Count column width instead of the number of code points. This also
includes correct handling of tabs inside string literals and comments (with an
exception of multiline string literals/comments, where tabs are present before
the first escaped newline).

Alexander Kornienko ffcc010767 UTF-8 support for clang-format.
Summary:
Detect if the file is valid UTF-8, and if this is the case, count code
points instead of just using number of bytes in all (hopefully) places, where
number of columns is needed. In particular, use the new
FormatToken.CodePointCount instead of TokenLength where appropriate.
Changed BreakableToken implementations to respect utf-8 character boundaries
when in utf-8 mode.
