5f53528867 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

7822e6aab5 Tiny patch for proof-of-concept cleanup of ARMAsmPrinter::EmitStartOfAsmFile() 
Small test for sanity check of resulting ARM .s file.
Tested against -r115129.

e4c0edf697 Move ELF to HasReliableSymbolDifference=true. Also take the opportunity to put 
symbols defined in merge sections in independent atoms.

8a987c002e Add a InitSections method to the streamer interface. 
The ELF implementation now creates text, data and bss to match the gnu as
behavior.

The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.

A nice benefit is that -n is not required anymore when producing
ELF files.

5b005d087c Factoring and potential bug fix. The elf "flags" cannot be used as masks. 
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce
a STT_SECTION (3).

c0f16ab31a ELF_STB_Local is 0 so setting and checking it must be done specially

3aabb3eb53 Mark all common symbols external. This is not exactly correct but it lets apps 
link for now and can be adjusted later. Patch by Roman Divacky.
