ad350eb789 Simplify MCContext::(Next|Get)Instance 
- Allocate MCLabels in the context so they don't leak.
- Avoid duplicated densemap lookup.

1cf4bded13 move elf section uniquing to MCContext. Along the way 
merge XCore's section into MCSectionELF

60ff59e5c1 move macho section uniquing from MCParser and TLOF to MCContext where 
the compiler and asmparser now unique to the same sections.  This fixes
rdar://7835021.

8e4cf6f425 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

962d3d700b fix GetOrCreateTemporarySymbol to require a name, clients 
should use CreateTempSymbol() if they don't care about the
name.

1b10191d18 fix a memory leak yjasskin pointed out: MCSymbol is bump pointer 
allocated and thus not freed.  This is cool except that it contains
and std::string so the string data didn't get freed.  In any case
there is no reason to redundantly store the string data in the 
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

3eb55835b5 add a new CreateTempSymbol method, the use case for 
CreateTempSymbol vs GetOrCreateTemporarySymbol are
completely different.

554f323da8 eliminate MCContext::CreateSymbol and CreateTemporarySymbol. 
Add a new GetOrCreateTemporarySymbol method and a version that
takes a twine.

c5165c4258 MC: Switch MCContext value table to storing MCExprs.

1f70368155 llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table. 
- I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).

04f74d3510 sink uniquing of sections out of MCContext into the ELF and PECOFF TLOF implementations. 
MCContext no longer maintains a string -> section map.

7ead5b498b add some comments: MCContext owns the MCSections, but it bump pointer allocates 
them, so it doesn't have to explicitly free them.

a682cb61e7 split MCSection stuff out to its own .cpp file, add a new 
MCSectionWithKind subclass of MCSection.

610dfdece7 create sections with MCSection::Create instead of Context->getOrCreateSection. 
This is needed to allow polymorphic sections.

082dc70875 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.

61a6509f6a 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.
