most visually pleasing way of looking at the graph.

Controls whether libCompilerDriver should be loaded dynamically. By default this
is needed only on Win32, to make dynamic plugins work.

Windows variant, strerror_s, but I couldn't test that.
I'll update configure and config.h.in in a subsequent patch.

initialization of all targets (InitializeAllTargets.h) or assembler
printers (InitializeAllAsmPrinters.h). This is a step toward the
elimination of relinked object files, so that we can build normal
archives.

Also, there were a bunch of flags with no text in --help because the square
brackets were in the wrong place. I've fixed those too.

mutex support. LLVM_MULTITHREADED indicates (or will indicate) the ability to run LLVM itself across multiple threads, and requires atomics support.

disable building LLVM in thread-safe mode and print a nice warning.
Regenerate configure for these changes.

Should now work when building with objdir != srcdir and when llvm-gcc is not
available.
Thanks to Duncan Sands for testing and advice!

Configure was not actually regenerated, but the change last time only touched
this one line, so I'm being lazy and cheating by fixing it manually.

This changes the interpreter to use libffi. After this patch, the interpreter
will barely be able to call any external functions if built on a system without
libffi installed (just enough to pass 'make check' really). But with libffi,
we can now call any function that isn't variadic or taking a struct or vector
parameter (but pointer to struct is fine). Patch by Alexei Svitkine!

This requires a rebuild of 'configure' itself. I will be committing that next, but
built with the wrong version of autoconf. Somebody who has the right one, please update
it.
As a side-note, because of the way autoconf works, all built tools will link against
libffi, not just lli. If you know how to fix this, please let me know ...
