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.
