Log:
clang-format: [JS] fix indenting bound functions.
Summary:
The previous fix to force build style wrapping if the previous token is a
closing parenthesis broke a peculiar pattern where users parenthesize the
function declaration in a bind call:
fn((function() { ... }).bind(this));
This restores the previous behaviour by reverting that change, but narrowing
the special case for unindenting closing parentheses to those followed by
semicolons and opening braces, i.e. immediate calls and function declarations.
