The following functions were the only functions that updates the source file:
SourceManager::File::DisplaySourceLines()
SourceManager::File::FindLinesMatchingRegex()
But there we API calls that were using the SourceManager::File and asking it questions, like "is line 12 valid" and that might respond incorrectly if the source file had been updated.

Summary:
This commit moves the m_spawned_pids member from the common LLGS/Platform class to the plaform
specific part. This enables us to remove LLGS code, which was attempting to manage the
m_spawned_pids contents, but at the same time making sure, there is only one debugged process. If
we ever want to do multi-process debugging, we will probably want to replace this with a set of
NativeProcessProtocolSP anyway. The only functional change is that support for
qKillSpawnedProcess packet is removed from LLGS, but this was not used there anyway (we have the
k packet for that).

system, make a couple of additional checks to see if the
attach was denied via the System Integrity Protection that
is new in Mac OS X 10.11. If so, return a special E87
error code to indicate this to lldb.
Up in lldb, if we receive the E87 error code, be specific
about why the attach failed.
Also detect the more common case of general attach failure
and print a better error message than "lost connection".
I believe this code will all build on Mac OS X 10.10 systems.
It may not compile or run on earlier versions of the OS.
None of this should build on other non-darwin systems.

debugging optimized code. Adds new methods on Function/SBFunction
to query whether a given function is optimized. Adds a new
function.is-optimized format entity and changes the default
frame-format to append "[opt]" if the function was built with
optimization.
The only indication that a binary was built with optimization
that we have right now is the presence of the DW_AT_APPLE_optimized
attribute (DW_FORM_flag value 1) in the DW_TAG_compile_unit.
The absence of this flag may mean that the compile_unit was not
compiled with optimization, or it may mean that the producer
does not generate this attribute.
Currently this only works for dSYM debugging. When we create
the CompileUnit with dwarf-in-.o-file debugging we don't have
the attribute value yet so it's not set. I need to find the
flag value when we do start to read the .o file DWARF and
set the CompileUnit's status at that point - but haven't
done it yet.
I'm also going to add a mechanism for issuing warnings to users
such that they're only issued once in a debug session and
there is away for users to suppress these warnings altogether
via .lldbinit file settings. But I want to get this changeset
committed now that it's at a useful state.

The removal of in-process Linux debug support left a switch statement
with llvm::Triple::FreeBSD as the only case. Simplify by replacing it
with a now-equivalent assertion.

As of r240543 ProcessPOSIX and POSIXThread are used only on FreeBSD, so

Summary:
Handle_k was printing an error when killing a process because KillSpawnedProcess was expecting to
be asynchronously notified of the process death, which no longer works, since we don't wait for
the process on a separate thread. However, the whole usage of KillSpawnedProcess is dubious here,
since it tries to be nice and terminate the process first with SIGTERM, which will not have the
intended effect on a ptraced process. I replace this code with a call to
NativeProcessProtocol::Kill, which does not suffer from these problems.

The command "-break-insert ns::foo" for function 'foo' in namespace 'ns'
was being parsed as file:function. This patch fixes these cases by adding
checks for '::'. (Note: '::func' is not parsed correctly by lldb due to
llvm.org/pr24271).

Also don't add the paths to the path mapping when DebugSymbols tells up about files, since

Summary:
For certain data structures, when the synthetic child provider returns
zero children, a summary like "Empty instance of <typename>" could be
more appropriate than something like "size=0 {}". This new option helps
hide the trailing "{}".
This is also exposed with a -h option for the command "type summary add".

The kernels_found variable is not initialized, so if it is not assigned true on line 823, then it will be a garbage value in the branch condition on line 828. This patch initializes the variable to false.
