d117fbb231 If we have a DIE with an AT_specification use that instead of the normal 
addr DIE when adding to the dwarf accelerator tables.

b80f778bd3 Get rid of an optimization in SCCP which appears to have many issues. Specifically, it doesn't handle many cases involving undef correctly, and it is missing other checks which 
lead to it trying to re-mark a value marked as a constant with a different value.  It also appears to trigger very rarely.

Fixes PR11357.

169698095d Remove a really ancient line from the default 'make clean' rule that attempts 
to delete core files.  This causes a warning in clang/lib/StaticAnalyzer on
case insensitive filesystems, since it contains a "Core" directory.  Since this
is pointless anyway, just zap it.

623a7e146b Use a bigger hammer to fix PR11314 by disabling the "forcing two-address 
instruction lower optimization" in the pre-RA scheduler.

The optimization, rather the hack, was done before MI use-list was available.
Now we should be able to implement it in a better way, perhaps in the
two-address pass until a MI scheduler is available.

Now that the scheduler has to backtrack to handle call sequences. Adding
artificial scheduling constraints is just not safe. Furthermore, the hack
is not taking all the other scheduling decisions into consideration so it's just
as likely to pessimize code. So I view disabling this optimization goodness
regardless of PR11314.
