6e72048add This is the first patch to put the needed bits in place to eventually allow code
to be aligned with optimal nops.  This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output.  Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output.  There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

111a3193b5 use EmitLinkage for functions as well as globals. One output
change is that we now use ".linkonce discard" for global variables

strict.  If anyone is interested in mcizing MCSection for COFF targets,
this should be easy to fix.

cee63322ea 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.

f9f93e4388 resolve a fixme: the "nonexecutable stack directive" is actually
a .section.  Switch to it with SwitchSection.

However, I think that this directive should be safe on any ELF target.
If so, we should hoist it up out of the X86 and SystemZ targets.

c7b8814bb4 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but
