These are cases that are implementing the "convert an exception to a Promise"
steps of the Web IDL spec. Typically the exception is thrown in the current
compartment; the Promise returned should simply match that. Otherwise we can
end up with a situation in which the promise doesn't actaully have access to
its rejection value, which will cause problems if someone uses then() on the
promise: the return value of the then() call will get a sanitized exception
instead of the real one.
We _could_ try to match the actual compartment of the exception, in theory.
But it's not clear why this would be preferable to using the current
compartment, even if there were cases in which the exception _doesn't_ match
the current compartment. Which there likely are not.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
