Mark Mentovai 50ed179e9a Use BUILDFLAG for OS checking
Use BUILDFLAG(IS_*) instead of defined(OS_*).

This was generated mostly mechnically by performing the following steps:
 - sed -i '' -E -e 's/defined\(OS_/BUILDFLAG(IS_/g' \
                -e 's%([ !])OS_([A-Z]+)%\1BUILDFLAG(IS_\2)%g' \
       $(git grep -l 'OS_'
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - sed -i '' -e 's/#ifdef BUILDFLAG(/#if BUILDFLAG(/' \
       $(git grep -l '#ifdef BUILDFLAG('
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - gsed -i -z -E -e \
       's%(.*)#include "%\1#include "build/buildflag.h"\n#include "%' \
       $(git grep -l 'BUILDFLAG(IS_'
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - Spot checks to move #include "build/buildflag.h" to the correct parts
   of files.
 - sed -i '' -E -e \
       's%^(#include "build/buildflag.h")$%#include "build/build_config.h"\n\1%' \
       $(grep -L '^#include "build/build_config.h"$'
         $(git grep -l 'BUILDFLAG(IS_'
           '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm'))
 - Add “clang-format off” around tool usage messages.
 - git cl format
 - Update mini_chromium to 85ba51f98278 (intermediate step).
   TESTING ONLY).
 - for f in $(git grep -l '^#include "build/buildflag.h"$'
              '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm'); do \
       grep -v '^#include "build/buildflag.h"$' "${f}" > /tmp/z; \
       cp /tmp/z "${f}"; done
 - git cl format
 - Update mini_chromium to 735143774c5f (intermediate step).
 - Update mini_chromium to f41420eb45fa (as checked in).
 - Update mini_chromium to 6e2f204b4ae1 (as checked in).

For ease of review and inspection, each of these steps is uploaded as a
new patch set in a review series.

This includes an update of mini_chromium to 6e2f204b4ae1:

f41420eb45fa Use BUILDFLAG for OS checking
6e2f204b4ae1 Include what you use: string_util.h uses build_config.h
