171de656eb An initial implementation of an LLVM ProfileInfo class which is designed to
eventually allow Passes to use profiling information to direct them.

376ad9fa9f Remove and simplify some of the bewildering collection of isFOORegister
methods which have strangely different semantics in different backends,
and noone knew what any did.

Getting rid of these ALSO allows the dependence of MachineInstr.h on
MRegisterInfo.h to be removed, which makes me much happier, and probably
alkis too.  :)

f32f56862a Now that all of the derived types have disciplined interfaces, we can eliminate
all of the ad-hoc storage of contained types.  This allows getContainedType to
not be virtual, and allows us to entirely delete the TypeIterator class.

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.

e88280a422 Add option to join live intervals. Two intervals are joined if there
is a move between two registers, at least one of the registers is
virtual and the two live intervals do not overlap.

This results in about 40% reduction in intervals, 30% decrease in the
register allocators running time and a 20% increase in peephole
optimizations (mainly move eliminations).

The option can be enabled by passing -join-liveintervals where
appropriate.

26bfc08b80 Add coalescing to register allocator. A hint is added to each interval
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

provides for future extensibility, might help the LLVA project avoid having to
hack their own LLI, and provides support required for the experimental Venus

dbd9b3f75c Hrm is a really nasty ommission. The lack of this destructor was causing abstract
types to never be deleted, manifesting itself as many OpaqueType objects being
leaked.  Whoops.

71499ded4d Add TwoAddressInstructionPass to handle instructions that have two or
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.
