Stephen Wilson f3e78a3040 Simple makefile fixups.
With the current target revision of Clang libclangChecker no longer exists and
is not needed.  Update the include path so we can get at ARM_DWARF_Registers.h
and friends.

Stephen Wilson 2103e25e19 Initial support for a DynamicLoader plugin on Linux.
This patch is enough to have shared objects recognized by LLDB.  We can handle
position independent executables.  We can handle dynamically loaded modules
brought in via dlopen.

The DYLDRendezvous class provides an interface to a structure present in the
address space of ELF-based processes.  This structure provides the address of a
function which is called by the linker each time a shared object is loaded and
unloaded (thus a breakpoint at that address will let LLDB intercept such
events), a list of entries describing the currently loaded shared objects, plus
a few other things.

On Linux, processes are brought up with an auxiliary vector on the stack.  One
element in this vector contains the (possibly dynamic) entry address of the
process.  One does not need to walk the stack to find this information as it is
also available under /proc/<pid>/auxv.  The new AuxVector class provides a
convenient read-only view of this auxiliary vector information.  We use the
dynamic entry address and the address as specified in the object file to compute
the actual load address of the inferior image.  This strategy works for both
normal executables and PIE's.

Stephen Wilson 842a9bac48 Makefile updates.
Update lib/Makefile to use current LLVM and Clang components and add the
PluginUtility library to the build.

Greg Clayton 2bddd3442f Patch from Jay Cornwall that modifies the LLDB "Host" layer to reuse more
code between linux, darwin and BSD.

Thanks again to William Lynch!

Stephen Wilson 4ec3fb9353 Fix makefiles to build properly on Darwin.

Stephen Wilson e6f9f66b39 Add a new Process plugin for Linux.
This component is still at an early stage, but allows for simple
breakpoint/step-over operations and basic process control.

The makefiles are set up to build the plugin under Linux only.

Greg Clayton c8e11e17aa Patch from Jean-Daniel Dupas:
Makefile patch to explicitly use PROJ_SRC_DIR when required. It fixes 
        build when obj dir is not source dir. 

I also fixed a build warning in ClangResultSynthesizer.cpp.

Eli Friedman 098039e4f0 Make current Makefiles work on Linux (at least, they work for me). Please
tell me if this breaks anything.

Greg Clayton c982c768d2 Merged Eli Friedman's linux build changes where he added Makefile files that
enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
