c420ab6c25 When building local graphs, clone the initializer for constant globals into each 
local graph that uses the global.

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.

239644dc3b Further reduce the number of nodes cloned with getClonedNH, using merge instead. 
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

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.
