04b7593546 Implement mod/ref analysis for a trivial case where locals don't escape. 
This comes up when you have a local array on the stack and you never pass
the address of elements around.

dbbbfef165 If we have edge counts, we can produce block counts. I've verified that 
using an edge profile to produce block counts gives the exact same numbers
as using a block count directly.

do it on povray.  The problem is that we were not copying globals from callees to
callers unless the existed in both graphs.  We should have copied them in the case
where the global pointed to a node that was copied as well.

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

Make the incompleteness marker faster by looping directly over the globals
instead of over the scalars to find the globals

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

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.

3b303d91d7 In a "seeing the forest through the trees" kinda situation, I realized that a 
complete rewrite of load-vn will make it a bit faster.  This changes speeds up
the gcse pass (which uses load-vn) from 25.45s to 0.42s on the testcase in
PR209.

I've also verified that this gives the exact same results as the old one.

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

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.

4d7af65903 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

50b5d71cb7 Make use of "external" depth-first iterators to avoid revisiting nodes 
multiple times.  This reduces the time to construct post-dominance sets a LOT.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.
