This patch includes a bunch of somewhat related fixes, these are:
- Ensuring that when a mochitest calls SimpleTest.expectChildProcessCrash()
the harness will wait for the crashes to be recorded before deleting the
dump files. This involves a message round-trip between the content and
parent process so to minimize its performance impact on all the non-crashing
tests it is done only when required.
- As an additional optimization, the SimpleTest harness will not send a
message to the content process anymore whenever it receives an
ipc:content-shutdown event, instead it does it only for abnormal shutdowns.
- Manually fixing remaining mochitests causing crashes to wait for crashes to
be recorded before finishing and deleting the dump files.
- Modifying BrowserTestUtils.crashBrowser() so that it optionally does not
delete the dump files, this is useful for tests that submit their dumps and
thus delete them on their own.
