This change makes significant improvements in the performance of
calculating a UUID within ObjectFileELF, and handles both running
processes and core files correctly. This does lazy evaluation of
UUID generation and caches the result when calculated.

Change by Piotr Rak.

When there was no process, the expression options were set to not ignore breakpoints. This causes debug info to be generated and causes errors when evaluating simple expressions.

Make "disassemble -a" work when the target is not running yet.  It will dump all the functions matching that address, just like "disassemble -n" does before running.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")

First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.

Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

Previous check relied on -DLLDB_DISABLE_PYTHON which was not valid as
it is defined in the top level LLDB Makefile which is included after the check.
If this check is moved after the inclusion of top level Makefile then 
BUILT_SOURCES is not properly handled. So I am using the scheme present
in the Host/Makefile.

This is a mechanical cleanup of unused functions.  In the case where the
functions are referenced (in comment form), I've simply commented out the
functions.  A second pass to clean that up is warranted.

The functions which are otherwise unused have been removed.  Some of these were
introduced in the initial commit and not in use prior to that point!

TestPromptFormats appears as though it may be a useful unit test.
Unfortunately, there is no invocation mechanism in place right now.  It is
unclear how to add a unit test for this scenario to the existing tests.  It
would be ideal to remove this entirely, but I am hopeful that this can/will be
pulled out into a test still since it uses a user accessible interface.

The standard JIT has been discarded in favour of MCJIT.  USE_STANDARD_JIT is no

IRExecutionUnit.  Simply remove inclusion of both JIT headers.

Multichar constants are not portable as the byte order is undefined.  Use a
constant value instead.  This avoids a warning when compiling with gcc 4.8+
(-Wmultichar) and makes the code more portable.

libxml2's include path was unconditionally set to /usr/include/libxml2.  This
would work previously, however, Mavericks removed the /usr/include directory.
Since LLDB already requires clang, which via LLVM's build infrastructure
searches for libxml2, we have a proper include path for libxml2.  If
LIBXML2_FOUND is set, do not touch the libxml2 search path.  Instead, allow the
clang's definition to propagate throughout the LLVM build.  Otherwise, switch to
find_package(LibXml2) as clang does.  This will ensure that the correct path is
used for libxml2 irrespective of the platform.

Furthermore, treat libxml2 as a system provided library.  It is not part of the
LLVM source base so it is of little value to enable all warnings on its headers.
This unifies the treatment of libxml2 across clang and LLDB.
