Bill Wendling da3e7547fb Believe it or not, this is a simplification. :-) 
Basically, this patch is working towards removing the hard-coded values that are
output for the CIE. In particular, the CIE augmentation and the CIE augmentation
size. Both of these should be calculated. In the process, I was able to make a
bunch of code simpler.

The encodings for the personality, LSDA, and FDE in the CIE are still not
correct. They should be generated either from target-specific callbacks (blech!)
or grokked from first-principles.

Bill Wendling e98ee2a534 - Rename EmitCommonInformationEntry to EmitCIE. 
- Rename EmitFunctionDescriptionEntry to EmitFDE.

Bill Wendling d7ace1e530 Rename functions to something more descriptive. At the very least mention the 
CIE and FDE in their names.

Chris Lattner 7b26fce23e Rename TargetAsmInfo (and its subclasses) to MCAsmInfo.

Jim Grosbach 486be66dbd Move the sjlj exception handling conversions to a back-end pass where they 
more properly belong. This allows removing the front-end conditionalized
SJLJ code, and cleans up the generated IR considerably. All of the
infrastructure code (calling _Unwind_SjLj_Register/Unregister, etc) is
added by the SjLjEHPrepare pass.

Jim Grosbach 693e36a3e8 SjLj based exception handling unwinding support. This patch is nasty, brutish 
and short. Well, it's kinda short. Definitely nasty and brutish.

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Built on Darwin and verified no llvm-core "make check" regressions.

Bill Wendling b67440efb8 - Temporarily unbreak the build by forcing the TType "absptr", which isn't 
correct. But what are you going to do? I'll fix this in the future.
- Move another large loop into its own method.

Again, no intendtional functionality change.

Bill Wendling d64cd2bb6e Split out the DwarfException class into its own file. No functionality change, 
though the classes have been marked with "VISIBILITY_HIDDEN".
