a3facc5cb5 further simplify EmitAlignment by eliminating the 
ForcedAlignBits argument, tweaking the single client of it.

64d43d80be round zero-byte .zerofill directives up to 1 byte. This

6a5e706e3c on darwin empty functions need to codegen into something of non-zero length, 
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505

f740a8ceeb fix PR6921 a different way. Intead of increasing the 
alignment of globals with a specified alignment, we fix
common variables to obey their alignment.  Add a comment
explaining why this behavior is important.

preferred alignment unless they were common or some other special
case.

5100367ff3 Bill's change in r95336 broke empty aggregates embedded 
in other types.  fix this by only bumping zero-byte globals
up to a single byte if the *entire global* is zero size,
fixing PR6340.

This also fixes empty arrays etc to be handled correctly,
and only does this on subsection-via-symbols targets (aka
darwin) which is the only place where this matters.

4a4710a055 clean up the asmprinter interface a bit, rename a few 
"Print" methods to "Emit".  Emit is something that goes
to an mc streamer, Print is something that goes to a
raw_ostream (for inline asm)

d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all 
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

86d61b5837 start moving towards emitting inline asm statements with 
EmitInlineAsm.  However, this attempt is foiled by operands
being emitted directly to "O" so I'll have to do some surgery
and finish MCizing the world.
