40bbeb5d07 Add a new ConstantAggregateZero class, to fix PR239. This makes zero
initializers for constant structs and arrays take constant space, instead of
space proportinal to the number of elements.  This reduces the memory usage of
the LLVM compiler by hundreds of megabytes when compiling some nasty SPEC95
benchmarks.

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.

376ad9fa9f Remove and simplify some of the bewildering collection of isFOORegister
methods which have strangely different semantics in different backends,

MRegisterInfo.h to be removed, which makes me much happier, and probably
alkis too.  :)

4ff0b9636d Substantially improve the DSA code by removing 'forwarding' nodes from
DSGraphs while they are forwarding.  When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted.  This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

2cca3008e8 One of the 'annoying' things about ilists is that the iterators don't behave
quite the same as for non-intrusive lists of pointers to nodes.  To support
transitioning code bases, add a new 'compatibility' iterator.

bidirectional, not random access.
