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.

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.

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.

When modifying an implicit instantiation with information from an explicit one, make sure to reset the "right brace" location.

Otherwise the source range of the explicit instantiation may become invalid (begin location will be after the end location).

This handles the false positive leak warning in PR15374, and also serves
as a basic model for the strsep() function.

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

Move implementation of MDNode::getMostGenericTBAA to TypeBasedAliasAnalysis.cpp
since it depends on how to interprete the MDNodes for scalar TBAA and
struct-path aware TBAA.

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.

Changed back (relative to commit 179786) the operations executed when extract(cast) is transformed to cast(extract). It uses the Builder class as before. In addition the result node is added to the Worklist, so all the previous extract users will become the new scalar cast users.
