ac1eaa43fa Implement a FIXME, improving the efficiency of DSA on povray.
This reduces CBU time from 145s -> 122s (debug build), reduces # allocated nodes
from 129420 to 116477.

bc7fc82865 Fix BU datastructures with povray!
The problem was that we were merging a field of a node with a value that was
deleted.  Thanks to bugpoint for reducing povray to a nice small 3 function
example.  :)

e0c90cf983 Minor changes, remove some debugging code that got checked in somehow.
Make sure to scope the NodeMap passed into cloneInto so that it doesn't point
to nodes that are deleted.  Add some FIXME's for future performance enhancements.

790bd9d970 Only clone nodes that are needed in the caller, don't clone ALL aux calls. This improves
povray from having ~600K nodes and 300K call nodes to 65K nodes and 25K call nodes.

0e1cd00f2c Fix a DSA bug that caused DSA to generate incredibly huge graphs and take forever to
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.

6978f97701 SPECIFY a target data to initialize the CBE target with. Until now we have
been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!

b78f8498f0 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
