mmap() the entire object file contents into memory with MAP_PRIVATE.
We do this because object file contents can change on us and currently
this helps alleviate this situation. It also make the code for accessing
object file data much easier to manage and we don't end up opening the
file, reading some data and closing the file over and over.

Fix DWARF parsing issue we can run into when using llvm-gcc based dSYM files.

Also fix the parsing of objective C built-in types (Class, id and SEL) so
they don't parse more information that is not needed due to the way they
are represented in DWARF.

This allows the selector identifier locations machinery for ObjCMessageExpr
to function correctly, in that there are not real locations to handle/report for
such a message.

To simplify the process:
Refactor taint generation checker to simplify passing the
information on which arguments need to be tainted from pre to post
visit.

Todo: We need to factor out the code that sema is using to identify the
string and memcpy functions and use it here and in the CString checker.

In att style asm syntax memory operand size is derived from suffix attached with mnemonic.  In intel style asm syntax it is part of memory operand hence predicate method check is required to select appropriate instruction.

same pattern. We already had this pattern is a few places, but others
tried to make a rough approximation of an actual DAG structure. As not
everywhere went to this trouble, nothing could rely on this being done.
In fact, I've checked all references to these node Ids, and the ones
that are using the topo-sort properties are actually satisfied with
a strict-weak-ordering. The requirement appears to be that Use >= Def.

I've added a big blurb of comments to this bit of the transform to
clarify why the order is so important for the next reader of the code.

I'm starting with this change as it is very small, and trivially
reverted if something breaks or the >= above really does need to be >.
If that proves the case, we can hide the problem by reverting this
patch, but the problem exists elsewhere as well, and so a more
comprehensive solution will be needed.

SBProcess.GetSTDERR() not getting stderr of the launched process

Since we are launch the inferior with:

    process = target.LaunchSimple(None, None, os.getcwd())

i.e., without specifying stdin/out/err.  A pseudo terminal is used for
handling the process I/O, and we are satisfied once the expected output
appears in process.GetSTDOUT().

Initial implementaiton of __dynamic_cast.  There is still lots of debugging code in here that needs to be stripped out.  And many, many unit tests need to be written.  And comments and probably code cleanliness needs to be improved.  But I *think* the basic algorithm is sound.  There also may still be some oportunities for algorithm optimization, I'm not positive.

Also fix a copy-and-paste error in a comment from my previous commit.
Finally, add an example of the benefit the typo correction callback adds
to TryNamespaceTypoCorrection--which happens to also tickle the above
caching problem, as the only way a non-namespace Decl would be added to
the possible corrections is if it was cached as the correction for a
previous instance of the same typo where the typo was corrected to a
non-namespace via a different code path.

Previously let the JITEmitter do it. That's rather odd, and doesn't play nice
with the MCJIT, so move the (trivial) logic up.
