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.

Chris Lattner dca25f69ca trivial QoI improvement. On this invalid input: 
sahf	movl	344(%rdi),%r14d
we used to produce:

t.s:2:1: error: unexpected token in argument list

^

we now produce:
t.s:1:11: error: unexpected token in argument list

Jim Ingham 773d981ce2 The thread plan destructors may call Thread virtual methods. That means they have to get cleaned up in the derived class's destructor. Make sure that happens.

Chris Lattner 8930615e78 patch from Frits van Bommel: 
The attached patch fixes IRBuilder and the NoFolder class so that when
NoFolder is used the instructions it generates are treated just like
the ones IRBuilder creates directly (insert into block, assign them a
name and debug info, as applicable).
It does this by
1) having NoFolder return Instruction*s instead of Value*s,
2) having IRBuilder call Insert(Value, Name) on values obtained from
the folder like it does on instructions it creates directly, and
3) adding an Insert(Constant*, const Twine& = "") overload which just
returns the constant so that the other folders shouldn't have any
extra overhead as long as inlining is enabled.

While I was there, I also added some missing (CreateFNeg and various
Create*Cast) methods to NoFolder.

Rafael Espindola 67c6ab8865 Change CodeGen to use .loc directives. This produces a lot more readable output 
and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.
