[analyzer] Be more consistent about Objective-C methods that free memory.
Previously, MallocChecker's pointer escape check and its post-call state
update for Objective-C method calls had a fair amount duplicated logic
and not-entirely-consistent checks. This commit restructures all this to
be more consistent and possibly allow us to be more aggressive in warning
about double-frees.
New policy (applies to system header methods only):
(1) If this is a method we know about, model it as taking/holding ownership
of the passed-in buffer.
(1a) ...unless there's a "freeWhenDone:" parameter with a zero (NO) value.
(2) If there's a "freeWhenDone:" parameter (but it's not a method we know
about), treat the buffer as escaping if the value is non-zero (YES) and
non-escaping if it's zero (NO).
(3) If the first selector piece ends with "NoCopy" (but it's not a method we
know about and there's no "freeWhenDone:" parameter), treat the buffer
as escaping.
The reason that (2) and (3) don't explicitly model the ownership transfer is
because we can't be sure that they will actually free the memory using free(),
and we wouldn't want to emit a spurious "mismatched allocator" warning
(coming in Anton's upcoming patch). In the future, we may have an idea of a
"generic deallocation", i.e. we assume that the deallocator is correct but
still continue tracking the region so that we can warn about double-frees.

r176010 introduced the notion of "interesting" lvalue expressions, whose
nodes are guaranteed never to be reclaimed by the ExplodedGraph. This was

the null or undef value being tracked.
However, the /rvalue/ nodes (i.e. the loads from these lvalues that produce
a null or undef value) /are/ still being reclaimed, and if we couldn't
find the node for the rvalue, we just give up. This patch changes that so

We were transforming the scope type of a pseudo-destructor expression
(e.g., the first T in x->T::~T()) as a freestanding type, which meant
that dependent template specialization types here would stay dependent
even when no template parameters were named. This would eventually
mean that a dependent expression would end up in what should be
fully-instantiated ASTs, causing IRgen to assert.

Assert to bounds check MDNode::getOperand.
The getOperandPtr utility already bounds checks, but allows one-off-the-end.
This assert should catch the cases that could previously have been dereferencing
these one-off-the-end pointer. Happily, no cases of this came up with this
change.

Initial checkin of a new project: LLDB Performance Testing Infrastructure
This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance
This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions
There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:
<?xml version="1.0" encoding="UTF-8"?>

Areas for improvement:
- code cleanups (I will be out of the office for a couple days this coming week, but please keep ideas coming!)
- more metrics and test cases
- better error checking
This toolkit also comprises a simple event-loop-driven controller for LLDB, similar yet much simpler to what the Driver does to implement the lldb command-line tool.

doing on Clang's behalf, and help with hopefully
