Reid Spencer a472f66dd0 For PR1146:
Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

Reid Spencer d3f622e0d5 Teach sys::Path how to recognize different kinds of object files for ELF
and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

Chris Lattner daa012d1fb Simplify SROA conversion to integer in some ways, make it more general in others.
We now tolerate small amounts of undefined behavior, better emulating what
would happen if the transaction actually occurred in memory.  This fixes
SingleSource/UnitTests/2007-04-10-BitfieldTest.c on PPC, at least until
Devang gets a chance to fix the CFE from doing undefined things with bitfields :)

Devang Patel 8eb8eeada9 Insert new pre-header before new header. Original pre-header may
happen to be an entry, in such case, it is not a good idea to
insert new block before entry.

Also fix typo in assertion check.

Reid Spencer ce38beb6a4 For PR1146:
* Add ParamAttrs to InvokeInst class too.
* Make sure all initializes of ParamAttrs in CallInst and InvokeInst are 0
* Destruct the ParamAttrs in Call/Invoke destructors to avoid memory
  leaks. This will change when ParamAttrsList is uniquified but needs to
  be correct until then.

Anton Korobeynikov 506eaf7915 Next stage into switch lowering refactoring
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.

Use ParamAttrsList for writing parameter attributes. Since they are sparse
now, we also write them sparsely (saves a few bytes). Unfortunately, this
