Teach the MC to output code/data region marker labels in MachO and ELF modes. These are used by disassemblers to provide better disassembly, particularly on targets like ARM Thumb that like to intermingle data in the TEXT segment.

Don't drop alignment info on local common symbols.
...
- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm
Based on a patch by NAKAMURA Takumi.
Fixes PR9337, PR9483 and PR10128.

eliminate the magic AbsoluteDebugSectionOffsets MAI hook,

which is really a property of the section being referenced.
Add a predicate to MCSection to replace it.
Yay for reduction in magic.

use EmitLinkage for functions as well as globals. One output
...
change is that we now use ".linkonce discard" for global variables
instead of ".linkonce samesize". These should be the same, just less
strict. If anyone is interested in mcizing MCSection for COFF targets,
this should be easy to fix.

Eliminate SetDirective, and replace it with HasSetDirective.
...
Default HasSetDirective to true, since most targets have it.
The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16. All of these except pic16 are normal ELF targets, so
they almost certainly have it.

I really want clients of the streamer to be able to say "emit this
