2792e203c5 For PR1146: 
Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

caf5a6cbd7 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.

4ea7a156ba 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 :)

a422b454ae Hack the shared library extension for dylib. The existing code just looks 
plain wrong since $module was never defined so we always get .so which is
broken on Darwin. Just force it to .dylib.

5392489e86 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.
