We use 'All' which is the default in the base LLVM style.
That's not the style we want but it works around the upstream
regression until clang-format 15.0 is released and widely used:
https://github.com/llvm/llvm-project/issues/54901
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Disable minimum amount of spaces in comment prefix for now, as it otherwise
modifies the whole codebase. That's something we probably want to use as it
matches our convention, but we should look into fully converting these
comments to our style guide at the same time.
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.
This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.
There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).
Part of #33027.
Part of #33027, also discussed in #29848.
Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.
For us, it practically only changes the fact that `A<A<int>>` is now
used instead of the C++03 compatible `A<A<int> >`.
Note: clang-format 10+ changed the `Standard` arguments to fully
specified `c++11`, `c++14`, etc. versions, but we can't use `c++17`
now if we want to preserve compatibility with clang-format 8 and 9.
`Cpp11` is still supported as deprecated alias for `Latest`.
Adapted some parameters to fit the de facto Godot style as closely as possible
(tab indentation, long lines with no wrapping - for now -, indented case labels,
left-aligned pointer operators).
