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

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

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.

There is probably a more elegant way to do this.

"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.
