b929bca027 Fix problem in DEBUG code. I could be pointing past the end and 
dereferencing it causes an assertion error.

b663d76f86 Modularize implementation of LeakDetector into a typed template 
implementation class. This makes the code simpler and allows for more
types to be added easily. It also implements caching for generic
objects (it was only available for llvm objects).

bb07ef97cf The prologue/epilogue related method calls have no reason to return a value, 
make them return void.

This allows us to avoid some costly MBB.size() calls

cc42d2c3cc A target that doesn't support these intrinsics will still meet spec (the 
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.

bc79471be1 Add next() and prior() iterator utility functions. Unlike std::advance 
they do not modify the passed iterator but return a copy.

next(myIt) returns copy of myIt incremented once
next(myIt, n) returns copy of myIt incremented n times
prior(myIt) returns copy of myIt decremented once
prior(myIt, n) returns copy of myIt decremented n times

While at it remove obsolete implementation of mapped_iterator.
