the alignment (because it's not encoded in DWARF). In this case, make
an educated guess at the alignment.

will ask ExternalASTSource objects to help laying out a type. This is needed
because the DWARF typically doesn't contain alignement or packing attribute
values, and we need to be able to match up types that the compiler uses
in expressions.

Sometimes there is only one 'resume' instruction per function. In those
situations, we don't need a separate block for the call to _Unwind_Resume. In
fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0.
If we have a single 'resume' instruction, just generate the call within that
block.

Sometimes it takes all day to write a decent comment.  This is one of those times, and I'm still not quite sure I have them correct.

because all functions are not C functions (i.e. NSLog).

Move to a model where we build whatever branches are checked out
in the source directories.  This was a bit too smart (and complicated)
in handling details best left to the user and the revision control
system.

In addition, get rid of support for llvm-gcc and building gcc as
these are no longer necessary.

Unfortunately I also had to disable constant-pool-sharing.ll the code it tests has been
updated to use the IL logic.

Updated ScheduleTopDownLive in MachineScheduler.cpp to use the moveInstr API
when reordering MIs.

that their owner reference is no longer valid.

single attribute ("system") that allows us to mark a module as being a
"system" module. Each of the headers that makes up a system module is
considered to be a system header, so that we (for example) suppress
warnings there.

If a module is being inferred for a framework, and that framework
directory is within a system frameworks directory, infer it as a
system framework.

Emit the message about putting ' -- ' between the end of command options and the raw input conditionally,
that is, only if the command object does not want completion.  An example is the "settings set" command.

Also added a few utilty functions that can be enabled for debugging issues
with modules staying around too long when external clients still have references
to them.

watching for errors from pthread_mutex_destroy () (usually "Resource
busy" errors for when you have a mutex locked and try to destroy
it), and pthread_mutex_lock, and pthread_mutex_unlock (usually for
trying to lock an invalid mutex that might have possible already
been freed).

ExecutionContext objects have shared pointers to Target, Process, Thread

map that tracks all live Module classes. We must leak our mutex for our
collection class as it might be destroyed in an order we can't control.

To test:
$ cl /c *.c*
in the asan directory.

The code fails to link if you omit the "/c" part but that's one of the
next steps,
as well as a few TODO's I've put into the Windows-specific code.

The double-extern thing is
http://llvm.org/bugs/show_bug.cgi?id=11869

And the #include <string[s].h> are only needed on Mac (see comments in
the original code)
and also including them might make strchr/index conflict with the g++
system headers (which don't follow the man pages, ouch!)

-Wno-everything remap all warnings to ignored.

We can now use "-Wno-everything -W<warning>" to ignore all warnings except
specific ones.
