6db8a9f3fa The sections that the ELF object writer has to create are very simple and 
contain only data. Handle them specially instead of using AddSectionToTheEnd.
This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.

9f44724be0 Rename temporary symbols if they conflict with artificial symbols created

example.

195a0ce484 Change some methods in MCDwarf.cpp to be able to handle an arbitrary 
MCStreamer instead of just MCObjectStreamer. Address changes cannot
be as efficient as we have to use DW_LNE_set_addres, but at least
most of the logic is shared.

This will be used so that, with CodeGen still using EmitDwarfLocDirective,
llvm-gcc is able to produce debug_line sections without needing an
assembler that supports .loc.

5c0556341e Change CodeGen to use .loc directives. This produces a lot more readable output

every address change anymore.
