Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Torok Edwin 6fb3e98eed Initialize CurSection in constructor. 
Not doing so causes some unittests to fail, because CurSection is uninitialized.

Daniel Dunbar f782ebc0cb We decided to not worry about Atoms for now, it should be straightforward to 
reintroduce them later.

Also, don't require MCSection* when creating a symbol.

Chris Lattner 3f5738d599 add trivial support for passing label definitions through the MCStreamer. 
This is suboptimal in several aspects, see the commented out assertion.
I need to talk to Daniel about this.
