Rafael Espindola 1614597873 Implement .weakref.

Rafael Espindola 8aefb66376 Improvements to .section parsing:
* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

Rafael Espindola eb0c2c170d Add support for the .symver directive. This is really ugly, but most of it is
contained in the ELF object writer.

Michael J. Spencer 3d89823102 MC: Move ParseDirectiveELFType into ELFAsmParser. COFF uses .type for something else.

Jan Wen Voung b96b2d8e4d Have ELFAsmParser.cpp use the already parsed "Size" (entry size) when
constructing a section. Test for a few cases also included.

Rafael Espindola f7f433200b Make sure that names like .note.GNU-stack are accepted as valid section names.

Rafael Espindola f667d929ce 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.

Daniel Dunbar 8897d479b5 MC/AsmParser: Stop playing unsafe member function pointer calls, this isn't
portable enough.
 - Downside is we now double dispatch through a stub function, but this isn't
   performance critical.
