Splitting basic blocks into multiple statements if there are now additional scalar dependencies gives more freedom to the scheduler, but more statements also means higher compile-time complexity. Switch to finer statement granularity, the additional compile time should be limited by the number of operations quota. The regression tests are written for the -polly-stmt-granularity=bb setting, therefore we add that flag to those tests that break with the new default. Some of the tests only fail because the statements are named differently due to a basic block resulting in multiple statements, but which are removed during simplification of statements without side-effects. Previous commits tried to reduce this effect, but it is not completely avoidable. Differential Revision: https://reviews.llvm.org/D42151 llvm-svn: 324169
