[ClangFormat] Add new style option IndentGotoLabels

Authored by tetsuo-cpp on Aug 31 2019, 4:05 AM.



This option determines whether goto labels are indented according to scope. Setting this option to false causes goto labels to be flushed to the left.
This is mostly copied from this patch submitted by Christian Neukirchen that didn't make its way into trunk.

true:                                  false:
int f() {                      vs.     int f() {
  if (foo()) {                           if (foo()) {
  label1:                              label1:
    bar();                                 bar();
  }                                      }
label2:                                label2:
  return 1;                              return 1;
}                                      }

This LGTM, just some minor Nits

1354 ↗(On Diff #218212)

could this just be

 // Align goto labels.
1973 ↗(On Diff #218212)

I think this could just be LeftAlignLabel, I'm not sure this function needs to know anything about goto specifically

1978 ↗(On Diff #218212)

then this would just be

if (LeftAlignLabel){
    Line->level = 0;
109 ↗(On Diff #218212)

Nit: maybe rename to just LeftAlignLabel

Addressed review comments.

Thanks for your suggestions! I think it's better now.
This is my first LLVM patch (hopefully first of many) so I don't have commit permissions yet. If you're still happy with this change, could you please commit on my behalf?
