It fixes obeying PointerAlignment for the ellipsis in variadic templates
(https://reviews.llvm.org/D83564), so patch all the files that use them.

clang-format 11 also introduces support for IndentCaseBlocks
(https://reviews.llvm.org/D72276), but leave that unused for now. The
default (false) does not change formatting.

Note that Chromium's buildtools comes with a version of clang-format
which claims to be 11.0.0 but is actually older and does not produce
the same formatting as the official release version:

instead.
