When retrieving element region, if its super region has binding, return

unknown for it.
Mark the super region of a live region as live, if the live region is pointed
to by a live pointer variable.
These fixes xfail_regionstore_wine_crash.c.

Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them.
...
The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.
This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.

Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.
...
This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control. There are many fixme's, but I think things are slightly
better than they were before.
One thing that can be improved: CFG should probably have an ASTContext pointer in it,
which would simplify its clients.
