Kyle Butt fef90abb68 CodeGen: BlockPlacement: Reduce TriangleChainCount to 2
This produces a 1% speedup on an important internal Google benchmark
(protocol buffers), with no other regressions in google or in the llvm
test-suite. Only 5 targets in the entire llvm test-suite are affected,
and on those 5 targets the size increase is 0.027%
