5447f9679d Change create*Pass factory functions to return Pass* instead of 
LoopPass*.
 - Although less precise, this means they can be used in clients
   without RTTI (who would otherwise need to include LoopPass.h, which
   eventually includes things using dynamic_cast). This was the
   simplest solution that presented itself, but I am happy to use a
   better one if available.

6564581be0 Enable first-class aggregates support. 
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

8b6f4366ae Tidy up BasicBlock::getFirstNonPHI, and change a bunch of places to 
use it instead of duplicating its functionality.

bab18cae46 Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

b54defaff0 Replace calls of the form V1->setName(V2->getName()) with V1->takeName(V2), 
which is significantly more efficient.

8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

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.
