[clang-format] restore indent in conditionals when AlignOperands is DontAlign
Summary:
After D50078, we're experiencing unexpected un-indent using a style combining `AlignOperands: DontAlign` with `BreakBeforeTernaryOperators: false`, such as Google's JavaScript style:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa =
bbbbbbbb ?
cccccccccccccccccc() :
dddddddddd ?
eeeeeeeeeeeeee :
fffff;
```
The issue lies with the interaction of `AlignOperands: DontAlign` and the edited code section in ContinuationIndenter.cpp, which de-dents the intent by `Style.ContinuationIndentWidth`. From [[ https://github.com/llvm/llvm-project/blob/
ac3e5c4d93fbe7fb2db3c745c721aff41cc1b851/clang/include/clang/Format/Format.h#L170 | the documentation ]] of AlignOperands: DontAlign:
> The wrapped lines are indented `ContinuationIndentWidth` spaces from the start of the line.
So the de-dent effectively erases the necessary `ContinuationIndentWidth` in that case.
This patch restores the `AlignOperands: DontAlign` behavior, producing:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa =
bbbbbbbb ?
cccccccccccccccccc() :
dddddddddd ?
eeeeeeeeeeeeee :
fffff;
```
