The existing AbortJS runtime function can be disabled via
--disable-abortjs (which the fuzzers use), but we never want to disable
CSA assertions. Hence use a separate runtime function for those.
This will also reduce the size of generated strings, since the
"CSA_ASSERT failed: " prefix is not part of those strings any more.

As a drive-by, this renames all occurences of "DebugAbort" to "AbortJS"
to be consistent in that name.
