082f484074 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.

996ec840d0 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.

b0d44c3807 refactor code so that LLVMTargetMachine creates the asmstreamer and
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.

73de5fbfc3 Give AsmPrinter the most common expected implementation of
runOnMachineFunction, and switch PPC to use EmitFunctionBody.
The two ppc asmprinters now don't heave to define 
runOnMachineFunction.

94a946cac4 Remove the argument from EmitJumpTableInfo, because it doesn't need it.
Move the X86 implementation of function body emission up to 
AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

1ff4794cbb eliminate the GVStubs and HiddenGVStubs maps, and use
MachineModuleInfoMachO instead.  This eliminates two sources
of nondeterministic output in the ppc backend, but function
stubs are still bad.

c7a062d187 Now that we have everything nicely factored (e.g. asmprinter is not
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:

6a160517a0 hoist handling of external globals and special globals up to common code.
This makes a similar code dead in all the other targets, I'll clean it up
in a bit.

This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

5b585f8b1a introduce a section kind for common linkage. Use this to slightly
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

1d371882b6 Cleanup handling of .zerofill on darwin:
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

209aecad0c change Mangler::makeNameProper to return its result in a SmallVector
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

7307bff420 The jump table was being generated before the end label for exception handling
was generated. This caused code like this:

Leh_func_end11:   ## <---now in the wrong section!

The `Leh_func_end11' would then end up in the wrong section, causing the
resulting EH frame information to be wrong:

__ZL11CheckRightsjPKcbRbRP6NSData.eh:
    .set    Lset500eh,Leh_frame_end11-Leh_frame_begin11
    .long   Lset500eh  ; Length of Frame Information Entry                                                                                                                   
Leh_frame_begin11:
    .long   Leh_frame_begin11-Leh_frame_common
    .long   Leh_func_begin11-.
    .set    Lset501eh,Leh_func_end11-Leh_func_begin11
    .long   Lset501eh                                   ; FDE address range                                                                                                                                   
`Lset501eh' is now something huge instead of the real value.

The X86 back-end generates the jump table after the EH information is
emitted. Do the same here.

10d3dc569b Instead of printing unnecessary basic block labels as labels in
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.
