The Language plugin is menat to answer language-specific questions that are not bound to the existence of a process. Those are still the domain of the LanguageRuntime plugin
The Language plugin will, instead, answer questions such as providing language-specific data formatters or expression evaluation
At the moment, the interface is hollowed out, and empty do-nothing plugins have been setup for ObjC, C++ and ObjC++

Older OSX versions don't define NSOperatingSystemVersion, so building
lldb gets: error: unknown type name 'NSOperatingSystemVersion'
This patch fixes the build by having GetOSVersionNumbers return false if
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ < 101000, causing lldb to
behave the same as it did before the commit.

Added a new class called DWARFDIE that contains a DWARFCompileUnit and DWARFDebugInfoEntry so that these items always stay together.
There were many places where we just handed out DWARFDebugInfoEntry pointers and then use them with a compile unit that may or may not be the correct one. Clients outside of DWARFCompileUnit and DWARFDebugInfoEntry should all be dealing with DWARFDIE instances instead of playing with DWARFCompileUnit/DWARFDebugInfoEntry pairs manually.
This paves to the way for some modifications that are coming for DWO.

This test runs fine on its own, but leaves python in a bad state to
where all tests that run after it error out. See llvm.org/pr24575.
This resolves the concerns raised in http://reviews.llvm.org/rL237053.

SUMMARY:
This patch implements Target::GetBreakableLoadAddress() method that takes an address
and checks for any reason there is a better address than this to put a breakpoint on.
If there is then return that address.
MIPS uses this method to avoid breakpoint in delay slot.

code that looks for a second stop-reply packet in response to an
interrupt (control-c). This is to handle the case where where a
stop packet is making its way up to lldb right as lldb decides to
interrupt the inferior. If the inferior is running and we interrupt
it, we'd expect a T11 type response meaning that the inferior halted
because of the interrupt. But if the interrupt gets a T05 type
response instead, meaning that we stopped execution by hitting a
breakpoint or whatever, then the interrupt was received while the
inferior was already paused and so it is treated as a "?" packet
-- the remote stub will send the stop message a second time.
There's a timeout where we wait to get this second stop reply packet
in SendContinuePacketAndWaitForResponse, currently 1ms. For a slow
remote target, it may take longer than that to send the second stop
reply packet. If that happens, then lldb will use that second stop
reply packet as the response for the next packet request it makes
to the remote stub. The two will be out of sync by one packet for
the rest of the debug session and it's going to go badly from then on.
I've seen times as slow as 46ms, and given the severity of missing that
second stop reply packet, I'm increasing the timeout to 100ms, or 0.1sec.

This updated patches correct problems in arm hardware watchpoint support patch posted earlier.
This patch has been tested on samsung chromebook (ARM - Linux) and PandaBoard using basic watchpoint test application.
Also it was tested on Nexus 7 Android device.
On chromebook linux we are able to set and clear all types of watchpoints but on android we end up getting a watchpoint packet error because we are not able to call hardware watchpoint ptrace functions successfully.

Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.
Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.
Bulk renames for things that used to return a ClangASTType which is now CompilerType:
"Type::GetClangFullType()" to "Type::GetFullCompilerType()"
"Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
"Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
"Value::GetClangType()" to "Value::GetCompilerType()"
"Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
"ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
many more renames that are similar.

Summary:
There were a number of issues about the way I have designed this test originally:
- it relied on single-stepping through large parts of code, which was slow and unreliable
- the threading libraries interfered with the exact thing we wanted to test
For this reason, I have rewritted the test using low-level linux api, which allows the test to be
much more focused. The functionality for other platforms will need to be tested separately.

The POSIX linker generally reports the load bias for the loaded
libraries but in some case it is useful to handle a library based on
absolute load address. Example usecases:
* Windows linker uses absolute addresses
* Library list came from different source (e.g. /proc/<pid>/maps)

Summary:
Most NPL private functions took (shared) pointers to threads as arguments. This meant that the
callee could not be sure if the pointer was valid and so most functions were peppered with
null-checks. Now, I move the check closer to the source, and pass around the threads as
references (which are then assumed to be valid).

Summary:
This commit implements basic DidAttach and DidLaunch for the windows
DynamicLoader plugin which allow us to load shared libraries from the
inferior.
At the moment, I'm unsure how we're going to gather the load address of
the main module over gdb protocol so I always use an offset of 0, which
works well for processes we create ourselves (no randomization). I will
address this point later on.

Summary:
When a windows remote stops because of a DLL load/unload, the debug server
sends a stop reply packet that contains a `library` key with any value (usually
just `library:1`). This indicates to the debugger that a library has been
loaded or unloaded and that the list of libraries should be refreshed (usually
with `qXfer:libraries:read`).
This change just triggers a call to `LoadModules()` which in turns will send a
remote library read command when a stop reply that requests it is received.
