LeadingComments affect breaking

[belav]

This affects ConstructorDeclarationSyntax and BaseMethodDeclarationSyntax.
IfStatementSyntax was easy to pull out the LeadingTrivia. This was less obvious. But looking at that may help.

Expected Formatting

namespace SomeNamespace
{
    public class ClassName
    {
        public void Exactly80(IApplicationBuilder app, IWebHostEnvironment env)
        {
            return;
        }

        // this shouldn't affect breaking
        public void Exactly80(IApplicationBuilder app, IWebHostEnvironment env)
        {
            return;
        }
    }
}

Actual Formatting

namespace SomeNamespace
{
    public class ClassName
    {
        public void Exactly80(IApplicationBuilder app, IWebHostEnvironment env)
        {
            return;
        }

        // this shouldn't affect breaking
        public void Exactly80(
            IApplicationBuilder app,
            IWebHostEnvironment env
        ) {
            return;
        }
    }
}

There are some more edge cases that need to be handled

public class ClassName
{
    void Method()
    {
        var fileContents = File.ReadAllText(file,
                // leading here should break parameters
                encoding ? GetEncoding(1252) : encoding, cancellationToken);

        var fileContents = File.ReadAllText(
            file,
                // leading here should break parameters and GetEncoding should still group
                encoding ? File.GetEncodinggggggggggggggg(
                        1252
                    ) : encodinggggggggggggggg,
            cancellationToken
        );

        var editorConfig = new Dictionary<string, string>() {
            // should break braces correctly
            ["asdfasdf"] = "none", ["asdf"] = "error", };
    }
}
