*	Switch spill weights from a basic loop depth estimation to BlockFrequencyInfo.	Benjamin Kramer	2013-06-17	1	-78/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The main advantages here are way better heuristics, taking into account not just loop depth but also __builtin_expect and other static heuristics and will eventually learn how to use profile info. Most of the work in this patch is pushing the MachineBlockFrequencyInfo analysis into the right places. This is good for a 5% speedup on zlib's deflate (x86_64), there were some very unfortunate spilling decisions in its hottest loop in longest_match(). Other benchmarks I tried were mostly neutral. This changes register allocation in subtle ways, update the tests for it. 2012-02-20-MachineCPBug.ll was deleted as it's very fragile and the instruction it looked for was gone already (but the FileCheck pattern picked up unrelated stuff). llvm-svn: 184105
