05a4c0b1f2 Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

9867c1a075 Rework global alignment computation again. Now we do round up 
alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common
case).

0d3490e0b0 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)

3eaaa7bb6c 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.

940911edf1 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.

4e8e791414 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

e7538fa303 rearrange MCContext ownership. Before LLVMTargetMachine created it 
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

db4b4d819d Move verbose asm instruction comments to using MCStreamer. 
The major win of this is that the code is simpler and they 
print on the same line as the instruction again:

        movl    %eax, 96(%esp)          ## 4-byte Spill
        movl    96(%esp), %eax          ## 4-byte Reload
        cmpl    92(%esp), %eax          ## 4-byte Folded Reload
