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.

dfab291702 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.

f67de7a69e alpha TAI doesn't need TM.

8d4a0a328a remove TargetAsmInfo::TM, which is now dead. The basic TAI class now
no longer depends on TM!

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.

9d8052f08f alpha doesn't need to redefine this: it only supports PIC codegen anyway.

01209bc12a Alpha always requires global relocations to be r/w regardless of PIC.

adding a TargetMachine member to the base TargetAsmInfo class instead.
