abcdf80ec6 The node doesn't have to be _no_ node flags, it just has to be complete and 
not have any globals.

cf14e71c5e Two changes: 
1. Functions do not make things incomplete, only variables
 2. Constant global variables no longer need to be marked incomplete, because
    we are guaranteed that the initializer for the global will be in the
    graph we are hacking on now.  This makes resolution of indirect calls happen
    a lot more in the bu pass, supports things like vtables and the C counterparts
    (giant constant arrays of function pointers), etc...

Testcase here: test/Regression/Analysis/DSGraph/constant_globals.ll

51c06abbf1 Simplify the dead node elimination stuff 
Make the incompleteness marker faster by looping directly over the globals
instead of over the scalars to find the globals

Fix a bug where we didn't mark a global incomplete if it didn't have any
outgoing edges.  This wouldn't break any current clients but is still wrong.

3567937f16 Instead of cloning the globals for main into the globals graph at the end of 
BU propagation, clone the globals into the GG of EACH FUNCTION that finishes
processing!  The GlobalsGraph *must* include all globals and effects from
all functions in the program.  Fixing this makes pool allocation work better
on 175.vpr, but it still ultimately crashes.

d10b5fd395 There is no need to merge the globals graph into the function graphs at the 
end of the BU and CBU passes.  The globals will be marked incomplete, so it
doesn't matter if they are missing some info, and merging isn't guaranteed
to bring everything in anyway!

68300db685 Add support for fopen/fclose. Specifically with fopen, we were marking all of the 
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

c3f5f7701f Instead of callign removeTriviallyDeadNodes on the global graph every time 
removeDeadNodes is called, only call it at the end of the pass being run.
This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is
pretty big.  This is only possible because of the automatic garbage
collection done on forwarding nodes.

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.

This reduces the number of nodes allocated, then immediately merged and DNE'd
from 2193852 to 1298049.  unfortunately this only speeds DSA up by ~1.5s (of
53s), because it's spending most of its time waddling through the scalar map :(

0b14487591 * Add a new commandline argument to control the "global roots hack". Default 
it to be off.  If it looks like it's completely unnecessary after testing, I
  will remove it completely (which is the hope).
* Callers of the DSNode "copy ctor" can not choose to not copy links.
* Make node collapsing not create a garbage node in some cases, avoiding a
  memory allocation, and a subsequent DNE.
* When merging types, allow two functions of different types to be merged
  without collapsing.
* Use DSNodeHandle::isNull more often instead of DSNodeHandle::getNode() == 0,
  as it is much more efficient.
*** Implement the new, more efficient reachability cloner class
    In addition to only cloning nodes that are reachable from interesting
    roots, this also fixes the huge inefficiency we had where we cloned lots
    of nodes, only to merge them away immediately after they were cloned.
    Now we only actually allocate a node if there isn't one to merge it into.
* Eliminate the now-obsolete cloneReachable* and clonePartiallyInto methods
* Rewrite updateFromGlobalsGraph to use the reachability cloner
* Rewrite mergeInGraph to use the reachability cloner
* Disable the scalar map scanning code in removeTriviallyDeadNodes.  In large
  SCC's, this is extremely expensive.  We need a better data structure for the
  scalar map, because we really want to scan the unique node handles, not ALL
  of the scalars.
* Remove the incorrect SANER_CODE_FOR_CHECKING_IF_ALL_REFERRERS_ARE_FROM_SCALARMAP code.
* Move the code for eliminating integer nodes from the trivially dead
  eliminator to the dead node eliminator.
* removeDeadNodes no longer uses removeTriviallyDeadNodes, as it contains a
  superset of the node removal power.
* Only futz around with the globals graph in removeDeadNodes if it is modified

2f561384fb Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

4c6cb7a2b1 Start implementing DSGraph::clonePartiallyInto and implement mergeInGraph 
in terms of it.

Though clonePartiallyInto is not cloning partial graphs yet, this change
dramatically speeds up inlining of graphs with many scalars.  For example,
this change speeds up the BU pass on 253.perlbmk from 69s to 36s, because
it avoids iteration over the scalar map, which can get pretty large.

1da1d32fc7 Rematerialize nodes from the globals graph into the current graph 
after all callees are inlined into the current graph.

NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp,
which ensures that resolvable indirect calls are not moved out to the
globals graph, so that they are eventually inlined (if possible).

03e19ddaf7 (1) Rematerialize nodes from the globals graph into the current graph 
after all callers are inlined into the current graph.
(2) Optimize the way a graph is inlined into its callees in the TD phase:
    (a) Use DSGraph::cloneReachableSubgraph to clone only a subgraph at
        each call site, for faster inlining.
    (b) Clone separately for the same callee at different call sites,
        since only the reachable subgraph is being cloned, not the entire
        caller graph.

78bbec7fcb Implement 2 important changes: (1) rematerialization from the globals graph, 
and (2) faster inlining by cloning only reachable nodes.  In particular:
(1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes
    to clone the subgraph reachable from a set of root nodes, into the
    current graph, merging the global nodes into thos in the current graph.
    The TD pass now uses this for faster inlining, and so does the
    next function.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
    globals graph into the current graph in both BU and TD passes.
(3) `I' flags are removed from all nodes in the globals graph, because they
    are difficult to maintain correctly and are not needed anyway.
(4) Aux. function calls are only removed to the globals graph if they
    will never be resovled.  (This is what fixed gap.)  The immediate
    reason is that if we took these out of a function (and moved them to
    the globals graph) we would need to rematerialize these nodes into the
    function graph for every function in the BU pass.  The longer term
    problem is that we would need to find a way to remove them from the
    globals graph iff they have been resolved on all paths through the
    call graph.

5f07a8b312 - Eliminate provably non-pointer nodes from graphs. 
This helps a lot of testcases, for example:
            New Time  New #Nodes     Old Time    Old #Nodes
254.gap:    91.1024     21605        91.1397     22657
povray31:    2.7807      8613         3.0152     10338
255.vortex:  1.2034      8153         1.2172     8822
moria:        .6756      3150          .7054     3877
300.twolf:    .1652      2010          .1851     3270

Typically, testcases which use long and ulong integers a lot get better, f.e. povray above.

2b7a92c72f Fix several related bugs in DSNode::mergeWith() caused by the 
fact that the incoming nodes may be merged away at intermediate
steps.  Use an extra level of indirection via DSNodeHandles
to track the nodes being merged.  All this now happens in a
static helper function MergeNodes().

9a96428297 (1) Bug fix that was causing nodes with dangling references to be freed. 
We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.
