*	Reapply the new LoopStrengthReduction code, with compile time and	Dan Gohman	2010-02-12	1	-6/+6

This change also flattens IVUsers, eliminating the stride-oriented groupings, which makes it easier to work with. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95975 91177308-0d34-0410-b5e6-96231b3b80d8

*	Re-implement the main strength-reduction portion of LoopStrengthReduction.	Dan Gohman	2010-01-21	1	-6/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This new version is much more aggressive about doing "full" reduction in cases where it reduces register pressure, and also more aggressive about rewriting induction variables to count down (or up) to zero when doing so reduces register pressure. It currently uses fairly simplistic algorithms for finding reuse opportunities, but it introduces a new framework allows it to combine multiple strategies at once to form hybrid solutions, instead of doing all full-reduction or all base+index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94061 91177308-0d34-0410-b5e6-96231b3b80d8
