Alexey Samsonov 068fc8ae6e Use zlib to uncompress debug sections in DWARF parser.
This makes llvm-dwarfdump and llvm-symbolizer understand
debug info sections compressed by ld.gold linker.

Jason Molenda 0f224d2cd4 Update the unwind_diagnose script to work correctly with both
lldb-179 version numberings and the new lldb-300 version numberings.
Remove the pretense that someone might run this from the command
line; this is only used from within a live lldb debug session.  Fix
the loading so it can be loaded via "script import lldb.macosx" or
the script can be loaded individually like "command script import
unwind_diagnose.py"

Tim Northover 2ac2d4c59d AArch64: remove unnecessary check that RS is valid
AArch64 always demands a register-scavenger, so the pointer should never be
NULL. However, in the spirit of paranoia, we'll assert it before use just in
case.

Jason Molenda 535ab8601f Add a new -a / --address argument to image show-unwind to get the
unwind instructions for a function/symbol which contains that
address.

Update the unwind_diagnose.py script to use this instead of doing
image show-unwind by name to avoid cases where there are multiple
name definitions.

Jason Molenda caae381b35 Add a new python file to help diagnose backtrace failures in the field.
It will be installed in the LLDB.framework and can be loaded with

  (lldb) script import lldb.macosx

after which a "unwind-diagnose" command will be registered.  Select
the thread which has a bad backtrace and run this command -- a lot
of information about the stack frames, and an alternate backtrace
algorithm, will be used.  The information will often be sufficient
for a remote person to figure out why the backtrace failed.

The tag is of type TBAANode when flag EnableStructPathTBAA is off.

Jordan Rose b957113b3f [analyzer] Treat reinterpret_cast like a base cast in certain cases.
The analyzer represents all pointer-to-pointer bitcasts the same way, but
this can be problematic if an implicit base cast gets layered on top of a
manual base cast (performed with reinterpret_cast instead of static_cast).
Fix this (and avoid a valid assertion) by looking through cast regions.

Using reinterpret_cast this way is only valid if the base class is at the
same offset as the derived class; this is checked by -Wreinterpret-base-class.
In the interest of performance, the analyzer doesn't repeat this check
anywhere; it will just silently do the wrong thing (use the wrong offsets
for fields of the base class) if the user code is wrong.
