[ScopBuilder] Make -polly-stmt-granularity=scalar-indep the default. 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

[ScopInfo] Do not add array name into memory reference ids Before this change a memory reference identifier had the form: <STMT>_<ACCESSTYPE><ID>_<MEMREF>, e.g., Stmt_bb9_Write0_MemRef_tmp11 After this change, we use the format: <STMT>_<ACCESSTYPE><ID>, e.g., Stmt_bb9_Write0 The name of the array that is accessed through a memory reference is not necessary to uniquely identify a memory reference, but was only added to provide additional information for debugging. We drop this information now for the following two reasons: 1) This shortens the names and consequently improves readability 2) This removes a second location where we decide on the name of a scop array, leaving us only with the location where the actual scop array is created. Having after 2) only a single location to name scop arrays will allow us to change the naming convention of scop arrays more easily, which we will do in a future commit to reduce compilation time. llvm-svn: 302004
