52d03b252e llvm-mc: Move AsmLexer::getCurStrVal to StringRef based API. 
- My DFS traversal of LLVM is, at least for now, nearly complete! :)

ee5513582d Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

dd27e5e10a Removed the SubsectionsViaSymbols MCStreamer API and replaced it with a generic 
EmitAssemblerFlag API which takes a value from the added AssemblerFlag
enumerated constants.

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").

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.

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

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.

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.
