bc01d5b148 Convert some more random-comment-printing stuff to use
AddComment and GetCommentOS.  Add a blank line between globals
(even in non-verbose mode) to make the assembly more readable.

df1b7b6164 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.

7c3ff46d45 add an MCAsmStreamer::EmitFill specialization of EmitFill that

6f360c3c91 now that MCSymbol::print doesn't use it's MAI argument, we can
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

4a33f01892 Change MCAsmStreamer to take an MCInstPrinter instead of a
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

2bb8df3b5d llvm-mc: Clean up some handling of symbol/section association to be more correct
(external was really undefined and there wasn't an explicit representation for
absolute symbols).

   with, but I haven't figured out the nicest approach yet.

b82fc63e02 Make AsmStreamer maintain a notion of the current section, pushing it up from the
MCAsmStreamer.  Based on this, eliminate the current section from AsmPrinter.

While I'm at it, clean up the last of the horrible "switch to null section" stuff
and add an assert.  This change is in preparation for completely eliminating 
asmprinter::switchtosection.
