Next step: Only pad debug_line when the target is darwin. Add a FIXME to avoid
...
doing that if the target is darwin10 or newer.
This fixes
*) Direct object emission was producing objects without the workaround on
darwin9.
*) Assembly printing was producing objects with the workaround on linux.

First step in fixing MC. Make it clear that we are avoiding a bug in the
...
darwin9 linker, what is needed to avoid it and where to get more information.
Also make the workaround simpler. Just the regular end_sequence we normally
create is more than 4 bytes.
Tested by building cctools and ld64 from darwin9 on a darwin10 system and using
those. I checked that I was able to reproduce the bootstrap failure when
the the workaround was disabled.

It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.

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.
