696d6ee9d7 Add some more debugging code, make it more obvious that RegOffset is 
getting an address for an object and select some default values.

926ba6058b Avoid O(n*m) complexity in StringRef::find_first(_not)_of(StringRef). 
- Cache used characters in a bitset to reduce memory overhead to just 32 bytes.
- On my core2 this code is faster except when the checked string was very short
  (smaller than the list of delimiters).

e0ed6ee921 Fix some GCC warnings by providing a virtual destructor in the base of a class 
hierarchy with virtual methods and using llvm_unreachable to properly indicate
unreachable states which would otherwise leave variables uninitialized.

a68e2a53a1 Revert invalid r111792. Jump tables are not broken on x86-64 / coff, 
it's COFF emitter which does not support differences of two symbols
(and needs to be fixed). GAS is pretty fine with code produced.

28d9071635 This is the first step towards refactoring the x86 vector shuffle code. The 
general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.

163660135e Create the new linker type "linker_private_weak_def_auto". 
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

072e7bdcd4 Introduce a new temporary MDNode concept. Temporary MDNodes are 
not part of the IR, are not uniqued, and may be safely RAUW'd.
This replaces a variety of alternate mechanisms for achieving
the same effect.
