Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

When extracting SEME regions of code, the extractor needs to update the dominator tree for split return blocks.

member templates declared inside other templates. This allows us to
match out-of-line definitions of member function templates within
class templates to the declarations within the class template. We
still can't handle out-of-line definitions for member class templates,
however.

reduce the size of relevant "ghostly" sentinels
by a pointer.

This attempt now makes the compactification dependent
on the configure variable LLVM_COMPACT_SENTINELS
and should not cause any bootstrap failures for
llvm-gcc any more.

Please note that this is not yet the final version,
and (as settled with Chris) I shall take out the
autofoo/cmake portions in the next days.

This will also lose the assertability on sentinel
dereferencing and operator++, but that seems
an acceptable price to pay for the simplified
build logic.
