c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

a7ac47cee1 Change TargetAsmInfo to be constructed via TargetRegistry from a Target+Triple
pair instead of from a virtual method on TargetMachine.  This cuts the final
ties of TargetAsmInfo to TargetMachine, meaning that MC can now use 
TargetAsmInfo.

98ca4f2a32 Major calling convention code refactoring.
Instead of awkwardly encoding calling-convention information with ISD::CALL,
ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering
provides three virtual functions for targets to override:
LowerFormalArguments, LowerCall, and LowerRet, which replace the custom
lowering done on the special nodes. They provide the same information, but
in a more immediately usable format.

This also reworks much of the target-independent tail call logic. The
decision of whether or not to perform a tail call is now cleanly split
between target-independent portions, and the target dependent portion
in IsEligibleForTailCallOptimization.

This also synchronizes all in-tree targets, to help enable future
refactoring and feature work.

1c55fab534 Don't flush the raw_ostream between each MachineFunction. These flush
calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.

Also, dropped uses of TargetMachine where unnecessary. The only target which
still takes a TargetMachine& is Mips, I would appreciate it if someone would
normalize this to match other targets.

f0144127b9 Rip all of the global variable lowering logic out of TargetAsmInfo. Since
it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.

Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.

This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
   pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
   CStringSection_.  Factor the code better.
5. fixes some bugs in string lowering on ELF targets.

targets change immutable objects later.
