Split the ENABLE_THREADS #define in two.  Now ENABLE_THREADS indicates the ability to run multiple threads at once in the JIT, and requires only
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!

Turns out that doing this by hand is easier than using autoreconf:-).

llvm-svn: 69475

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.

BUILT WITH WRONG VERSION OF AUTOCONF! Somebody please regenerate with an
approved version. Thanks!

turned "obj-c++" into "obj" in the langs line.
Update configure script.

llvm-svn: 57267

llvm-svn: 57233

Before there were two problems: (1) configure
turned "obj-c++" into "obj" in the langs line;
(2) the dejagnu library called it objc++ not
obj-c++.
Now the problem is that some of these tests don't
pass!

runnable on the build machine.

There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.

Thanks to Eric C. and Devang P. for pre-commit review.
