111a3193b5 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.

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.

86e2211d0a Add the ability for MCStreamer to emit comments on the same line as directives.
Switch over the asm-verbose comment for double values to use it.  We now get:

_x:
	.long	343597384                                   ## double 1.231200e+02
	.long	1079953326

For example, note that the comment is on the same line as the .long.  Woo.

e73a31f667 Stop building RTTI information for *most* llvm libraries. Notable
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

c7b8814bb4 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but
I really want clients of the streamer to be able to say "emit this

I may change this in the future, we'll see how it works out.
