d269a6e460 make MachineModuleInfoMachO hold non-const MCSymbol*'s instead
of const ones.  non-const ones aren't very useful, because you can't
even, say, emit them.

5669e30097 change addPassesToEmitFile to return true on failure instead of its input,
add -filetype=null for performance testing and remove -filetype=dynlib,
which isn't planned to be implemented.

d1ff72b8a7 rejigger the world so that EmitInstruction prints the \n at
the end of the instruction instead of expecting the caller to
do it.  This currently causes the asm-verbose instruction 
comments to be on the next line.

0d883e3f84 sink handling of target-independent machine instrs (other
than DEBUG_VALUE :(  ) into the target indep AsmPrinter.cpp
file.   This allows elimination of the 
NO_ASM_WRITER_BOILERPLATE hack among other things.

be2e76bbb3 make any use of the "O" stream in asmprinter print to
stderr if in filetype=obj mode.  This is a hack, and will
live until dwarf emission and other random stuff that is
not yet going through MCStreamer is upgraded.  It only
impacts filetype=obj mode.

ac7798e906 Hook up -filetype=obj through the MachO streamer. Here's a demo:
$ cat t.ll 
@g = global i32 42
$ llc t.ll -o t.o -filetype=obj
$ nm t.o
00000000 D _g

There is still a ton of work left.  Instructions are not being encoded
yet apparently.
