9f0512d85f Change directory_entry::path() to return a const std::string & instead of 
a StringRef, for the benefit of clients that want the result as a
nul-terminated string. Clients that expect a StringRef will get one via
the implicit conversion.

2d76ad6df9 Fix C++0x incompatibility. The signature of std::make_pair<> changes from: 
template <class T1, class T2> pair<T1,T2> make_pair(const T1&, const T2&);
to
  template <class T1, class T2> pair<V1, V2> make_pair(T1&&, T2&&);
so explicitly specifying the template arguments to make_pair<> is going to break
when C++0x rolls through. Replace them with equivalent std::pair<>. Patch by
James Dennett!

68e6beeccc Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

2cfbf018a9 If the phi node was used by an unreachable instruction that ends up using 
itself without going via a phi node then we could return false here in
spite of making a change.  Also, tweak the comment because this method
can (and always could) return true without deleting the original phi node.
For example, if the phi node was used by a read-only invoke instruction
which is used by another phi node phi2 which is only used by and only uses
the invoke, then phi2 would be deleted but not the invoke instruction and
not the original phi node.
