It set NumLowBitAvailable = 3 which may not be true on all platforms.  We only
ever use 2 bits (the default) so this assumption can be safely removed

Should fix PR12612.

clang/test/Rewriter/rewrite-modern-extern-c-func-decl.mm: Mark as XFAIL:mingw for now, due to predefined __declspec.

It could be tweaked to add -triple i686-win32, though.

Set the source location for the "member reference base type ... is not a
structure or union" diag to point at the operator rather than the member name.
If we're giving this diagnostic because of a typo'd '.' in place of a ';' at
the end of a line, the caret previously pointed at the identifier on the
following line, which isn't as helpful as it could be. Pointing the caret at
the '.' makes it more obvious what the problem is.

Added code to automatically load the libheap.dylib when ptr_refs, cstr_refs or malloc_info are called. If MallocStackLogging is enabled, then you can now use --stack to dump the backtrace of the code that allocated each malloc block.

The X86 target is editing the selection DAG while isel is selecting
nodes following a topological ordering. When the DAG hacking triggers
CSE, nodes can be deleted and bad things happen.

Fixed some issues with symbolicating things. Fixed symbolication.add_module() to not use the resolved_path before we have tried to locate it. Fixed crashlog.locate_module_and_debug_symbols() to return true and false correctly.

Now that multiple DAGUpdateListeners can be active at the same time,
ISelPosition can become a local variable in DoInstructionSelection.

We simply register an ISelUpdater with CurDAG while ISelPosition exists.

Instead of passing listener pointers to RAUW, let SelectionDAG itself
keep a linked list of interested listeners.

This makes it possible to have multiple listeners active at once, like
RAUWUpdateListener was already doing. It also makes it possible to
register listeners up the call stack without controlling all RAUW calls
below.

DAGUpdateListener uses an RAII pattern to add itself to the SelectionDAG
list of active listeners.

Per Greg Clayton:
libclang.dylib is trying to be smart and load itself at a valid address
to be able to load faster which would work for 32 bit systems,
bit won't make any difference on 64 bit systems.
It should either pick a better 64 bit address, or just let itself be loaded at zero.

This is needed to ensure that we always report issues in the correct
function. For example, leaks are identified when we call remove dead
bindings. In order to make sure we report a callee's leak in the callee,
we have to run the operation in the callee's context.

This change required quite a bit of infrastructure work since:
 - We used to only run remove dead bindings before a given statement;
here we need to run it after the last statement in the function. For
this, we added additional Program Point and special mode in the
SymbolReaper to remove all symbols in context lower than the current
one.
 - The call exit operation turned into a sequence of nodes, which are
now guarded by CallExitBegin and CallExitEnd nodes for clarity and
convenience.

(Sorry for the long diff.)

The <undef> flag on a def operand only applies to partial register
redefinitions. Only print the flag when relevant, and print it as
<def,read-undef> to make it clearer what it means.

Make sure the "synchronous breakpoint callbacks" get called before the thread plan logic gets invoked, and if they
ask to continue that should short-circuit the thread plans for that thread.  Also add a bit more explanation for
how this machinery is supposed to work.  
Also pass eExecutionPolicyOnlyWhenNeeded, not eExecutionPolicyAlways when evaluating the expression for breakpoint
conditions.
