Add handling of async notify packets
This patch adds a listener to the AynscThread in ProcessGDBRemote, specifically for dealing with any async notification packets.
From the broadcast our listener receives we can process the notify packet from the event data. A handler function then sets the thread stop info from this packet, and updates lldb by setting the process private state to stopped. Allowing the async thread to go back to sleep and getting the main thread to handle the implications of a state change.
When sending a vCont in nonstop mode we also get a different reply from all-stop mode, an OK response as opposed to a stop reply. So a condition is added to handle this and set the process state without the stop-reply data.

[MS ABI] Rework member pointer conversion
Member pointers in the MS ABI are made complicated due to the following:
- Virtual methods in the most derived class (MDC) might live in a
vftable in a virtual base.
- There are four different representations of member pointer: single
inheritance, multiple inheritance, virtual inheritance and the "most
general" representation.
- Bases might have a *more* general representation than classes which
derived from them, a most surprising result.
We believed that we could treat all member pointers as-if they were a
degenerate case of the multiple inheritance model. This fell apart once
we realized that implementing standard member pointers using this ABI
requires referencing members with a non-zero vbindex.
On a bright note, all but the virtual inheritance model operate rather
similarly. The virtual inheritance member pointer representation
awkwardly requires a virtual base adjustment in order to refer to
entities in the MDC.
However, the first virtual base might be quite far from the start of the
virtual base. This means that we must add a negative non-virtual
displacement.
However, things get even more complicated. The most general
representation interprets vbindex zero differently from the virtual
inheritance model: it doesn't reference the vbtable at all.
It turns out that this complexity can increase for quite some time:
consider a derived to base conversion from the most general model to the
multiple inheritance model...
To manage this complexity we introduce a concept of "normalized" member
pointer which allows us to treat all three models as the most general
model. Then we try to figure out how to map this generalized member
pointer onto the destination member pointer model. I've done my best to
furnish the code with comments explaining why each adjustment is
performed.
This fixes PR23878.

our conversion logical to convert it to the target type.
This allows us to simplify how we think about member pointers because we
don't need to consider non-zero nv adjustments before we even generate
the member pointer. Furthermore, it gives our adjustment logic more
exposure by utilizing it in a common path.

[x86] generalize reassociation optimization in machine combiner to 2 instructions
Currently ( D10321, http://reviews.llvm.org/rL239486 ), we can use the machine combiner pass
to reassociate the following sequence to reduce the critical path:
A = ? op ?
B = A op X
C = B op Y
-->
A = ? op ?
B = X op Y
C = A op B
'op' is currently limited to x86 AVX scalar FP adds (with fast-math on), but in theory, it could
be any associative math/logic op (see TODO in code comment).
This patch generalizes the pattern match to ignore the instruction that defines 'A'. So instead of
a sequence of 3 adds, we now only need to find 2 dependent adds and decide if it's worth
reassociating them.
This generalization has a compile-time cost because we can now match more instruction sequences
and we rely more heavily on the machine combiner to discard sequences where reassociation doesn't
improve the critical path.
For example, in the new test case:
A = M div N
B = A add X
C = B add Y
We'll match 2 reassociation patterns, but this transform doesn't reduce the critical path:
A = M div N
B = A add Y
C = B add X
We need the combiner to reject that pattern but select this:
A = M div N
B = X add Y
C = B add A

It contains an array of dicitionaries with all of the key value pairs that are normally in the stop reply packet. Including the expedited registers. Notice that is also contains expedited memory in the "memory" key. Any values in this memory will get included in a new L1 cache in lldb_private::Process where if a memory read request is made and that memory request fits into one of the L1 memory cache blocks, it will use that memory data. If a memory request fails in the L1 cache, it will fall back to the L2 cache which is the same block sized caching we were using before these changes. This allows a process to expedite memory that you are likely to use and it reduces packet count. On MacOSX with debugserver, we expedite the frame pointer backchain for a thread (up to 256 entries) by reading 2 pointers worth of bytes at the frame pointer (for the previous FP and PC), and follow the backchain. Most backtraces on MacOSX and iOS now don't require us to read any memory!
We will try these packets out and if successful, we should port these to lldb-server in the near future.

The _Int instructions are special, in that they operate on the full
