- if you have LLDB checked out in $llvm/tools, CMake will build it now!
- LLDB is known to build on Linux with libstdc++ and GCC 4.6/4.7 or Clang 3.3
- to run lldb tests, do "make check-lldb" after a build

- Consistency with opt (which supports the same option with the same meaning and
  description).
- Debugging gold plugin-based linking without optimizations getting in the way.
- Debugging programs linked with the gold plugin while preserving the original
  debug info.
- Fine-grained control over LTO passes using the gold plugin in combination with
  opt (or clang/dragonegg).

This changes the RecordingMemoryManager in lli to use mapped memory rather than malloc to allocate memory for sections and uses a 'near' MemoryBlock to keep the allocations together.  This works around a problem in MCJIT where relocations are applied to a generated image immediately oupon generation, which isn't appropriate for the remote case.

Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

Improve performance of iterating over children and accessing the member file
buffer by caching the file size and moving code out to the header.

This also makes getBuffer return a StringRef instead of a MemoryBuffer. Both
fixing a memory leak and removing a malloc.

This takes getBuffer from ~10% of the time in lld to unmeasurable.

isa<> and dyn_cast<>. In several places, code is already hacking around
the absence of this, and there seem to be several interfaces that might
be lifted and/or devirtualized using this.

This change was based on a discussion with Jim Grosbach about how best
to handle testing for specific MCStreamer subclasses. He said that this
was the correct end state, and everything else was too hacky so
I decided to just make it so.

No functionality should be changed here, this is just threading the kind
through all the constructors and setting up the classof overloads.

Add DIContext::getLineInfoForAddressRange() function and test.  This function allows a caller to obtain a table of line information for a function using the function's address and size.

Add support for applying in-memory relocations to the .debug_line section and, in the case of ELF files, using symbol addresses when available for relocations to the .debug_info section.  Also extending the llvm-rtdyld tool to add the ability to dump line number information for testing purposes.

Also patch llvm-dwarfdump to actually check whether the file it's attempting to

the message will be overwritten by the construction of the runner, resulting in
