Summary: NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]] This commit is the result of modernizing the LLDB codebase by using `nullptr` instread of `0` or `NULL`. See https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html for more information. This is the command I ran and I to fix and format the code base: ``` run-clang-tidy.py \ -header-filter='.*' \ -checks='-*,modernize-use-nullptr' \ -fix ~/dev/llvm-project/lldb/.* \ -format \ -style LLVM \ -p ~/llvm-builds/debug-ninja-gcc ``` NOTE: There were also changes to `llvm/utils/unittest` but I did not include them because I felt that maybe this library shall be updated in isolation somehow. NOTE: I know this is a rather large commit but it is a nobrainer in most parts.
