2c11eb333c Renumber slot indexes uniformly instead of spacing according to the number of defs. 
There are probably much larger speedups to be had by renumbering locally instead
of looping over the whole function. For now, the greedy register allocator is
25% faster.

f37712f486 Represent sentinel slot indexes with a null pointer. 
This is much faster than using a pointer to a ManagedStatic object accessed with
a function call. The greedy register allocator is 5% faster overall just from
the SlotIndex default constructor savings.

a97ff8a027 Avoid comparing invalid slot indexes, and assert that it doesn't happen. 
The SlotIndex created by the default construction does not represent a position
in the function, and it doesn't make sense to compare it to other indexes.

36d61863bc Cache basic block bounds instead of asking SlotIndexes::getMBBRange all the time.

DenseMap is not as fast as one might hope.

254c63e336 Avoid exponential blow-up when printing DAGs. 
David Greene changed CannotYetSelect() to print the full DAG including multiple
copies of operands reached through different paths in the DAG.  Unfortunately
this blows up exponentially in some cases.  The depth limit of 100 is way too
high to prevent this -- I'm seeing a message string of 150MB with a depth of
only 40 in one particularly bad case, even though the DAG has less than 200
nodes.  Part of the problem is that the printing code is following chain
operands, so if you fail to select an operation with a chain, the printer will
follow all the chained operations back to the entry node.

4670353a21 Transfer simply defined values directly without recomputing liveness and SSA.

38c4e53549 Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)
