Gabriel Ravier 7240436c94 [lldb] Fixed a number of typos
I went over the output of the following mess of a command:

  (ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel
  --xargs -0 cat | aspell list --mode=none --ignore-case | grep -E
  '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' |
  aspell pipe -W3 | grep : | cut -d' ' -f2 | less)

and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).
