Daniel Dunbar ce5e1bb326 MC: Add dyn_cast support to MCSection. 
- Of questionable utility, since in general anything which wants to do this should probably be within a target specific hook, which can rely on the sections being of the appropriate type. However, it can be useful for short term hacks.

Benjamin Kramer 0c1dcb083e XFAIL some PIC16 tests when running under valgrind-leaks. I don't expect these 
to be fixed any time soon.

Benjamin Kramer 7cc264bf19 PIC16: Plug a leak in PIC16Section by allocating name & address strings in the 
MCContext. There is still one leak left in PIC16Section (the Items vector).

Sanjiv Gupta 47ea743618 Add a pass to overlay pic16 data sections for function frame and automatic 
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph 
to detect what function frames and their automatic variables can be overlaid.
Currently this builds an archive , but needs to be changed to a loadable module.

Daniel Dunbar 3b5bdd536b Revert "Complete Rewrite of AsmPrinter, TargetObjectFile based on new 
PIC16Section class", it breaks globals.ll.

Chris Lattner 6362cbe64e rename PIC16Section.h -> MCSectionPIC16.h for consistency with 
the class it defines.

Chris Lattner 5ed8c4212a make PIC16 unique its own sections instead of having mcontext do it.

Chris Lattner 591105c540 sink the 'name' and 'isdirective' state out of MCSection into its derived classes. 
This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

Chris Lattner 1cb9396f4f 1. Make MCSection an abstract class. 
2. Move section switch printing to MCSection virtual method which takes a
   TAI.  This eliminates textual formatting stuff from TLOF.
3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and 
   TLOFELF::AtIsCommentChar.

Chris Lattner 26cc5b78d0 add new PIC16Section class, this time hopefully not breaking the build :)
