Johnny Chen 2cf3222029 Add stubs of incomplete watchpoint implementation with "FIXME" markers.

Greg Clayton 9414a367a1 Added the debug registers for i386 and x86_64 in preparation for watchpoints.

Sean Callanan c4ffe37cf1 Added support for dynamic detection of AVX, and
fixed a few bugs that revealed.  Now the "register
read" command should show AVX registers
(ymm0-ymm15) on Mac OS X platforms that support
them.

When testing this on Mac OS X, run debugserver
manually, like this:

debugserver --native-regs localhost:1111 /path/to/executable

Then

lldb /path/to/executable
...
(lldb) process connect connect://localhost:1111

Greg Clayton effe5c956b Added new OptionGroup classes for UInt64, UUID, File and Boolean values.
Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules". 

Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]

So you can load individual sections without running a target:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000

Or you can rigidly slide an entire shared library:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000

This should improve bare board debugging when symbol files need to be slid around manually.

Sean Callanan c530af05fe Added AVX support to the Intel portion of debugserver. AVX
autodetection is not yet implemented, but the structures and
register reading/writing code are there.

Greg Clayton c4e411ffc0 Thread safety changes in debugserver and also in the process GDB remote plugin.
I added support for asking if the GDB remote server supports thread suffixes
for packets that should be thread specific (register read/write packets) because
the way the GDB remote protocol does it right now is to have a notion of a
current thread for register and memory reads/writes (set via the "$Hg%x" packet)
and a current thread for running ("$Hc%x"). Now we ask the remote GDB server
if it supports adding the thread ID to the register packets and we enable
that feature in LLDB if supported. This stops us from having to send a bunch
of packets that update the current thread ID to some value which is prone to
error, or extra packets.

Greg Clayton 3af9ea56d3 Fixed Process::Halt() as it was broken for "process halt" after recent changes
to the DoHalt down in ProcessGDBRemote. I also moved the functionality that
was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has
to implement a tricky halt/resume on the internal state thread. The 
functionality is the same as it was before with two changes:
- when we eat the event we now just reuse the event we consume when the private
  state thread is paused and set the interrupted bool on the event if needed
- we also properly update the Process::m_public_state with the state of the
  event we consume.
  
Prior to this, if you issued a "process halt" it would eat the event, not 
update the process state, and then produce a new event with the interrupted
bit set and send it. Anyone listening to the event would get the stopped event
with a process that whose state was set to "running".

Fixed debugserver to not have to be spawned with the architecture of the
inferior process. This worked fine for launching processes, but when attaching
to processes by name or pid without a file in lldb, it would fail.

Now debugserver can support multiple architectures for a native debug session
on the current host. This currently means i386 and x86_64 are supported in
the same binary and a x86_64 debugserver can attach to a i386 executable.
This change involved a lot of changes to make sure we dynamically detect the
correct registers for the inferior process.
