Update the debugserver "qProcessInfo" implementation to return the
cpu type, cpu subtype, OS and vendor information just like qHostInfo
does so lldb can create an ArchSpec based on the returned values.

Add a new GetProcessArchitecture to GDBRemoteCommunicationClient akin
to GetHostArchitecture.  If the qProcessInfo packet is supported,
GetProcessArchitecture will return the cpu type / subtype of the 
process -- e.g. a 32-bit user process running on a 64-bit x86_64 Mac
system. 

Have ProcessGDBRemote set the Target's architecture based on the 
GetProcessArchitecture when we've completed an attach/launch/connect.

Jason Molenda fca9c6bb9f Add a new qProcessInfo packet to debugserver.
This can be used by lldb to ask for information
about the process debugserver is attached to/launched.
Particularly useful on a 64-bit x86 Mac system which
can run  32-bit or 64-bit user-land processes.

Jason Molenda cb349ee19c When unwinding from the first frame, try to ask the remote debugserver
if this is a mapped/executable region of memory.  If it isn't, we've jumped
through a bad pointer and we know how to unwind the stack correctly based
on the ABI.  

Previously I had 0x0 special cased but if you jumped to 0x2 on x86_64 one
frame would be skipped because the unwinder would try using the x86_64 
ArchDefaultUnwindPlan which relied on the rbp.

Greg Clayton bda72b83f4 I added more complete documentation on all of the new packets we use in LLDB
as well as attached a new priority description as to why and when you would
want to implement each packet.

Also documented the additions we have made to the stop reply packet and why
the extra information is necessary.

Greg Clayton 1167c4e379 Added some documentation on the new GDB remote packets we have added and use
in LLDB.
