[ScopBuilder] Introduce metadata for splitting scop statement. This patch allows annotating of metadata in ir instruction (with "polly_split_after"), which specifies where to split a particular scop statement.

[ScopBuilder] Revise statement naming when there are multiple statements per BB. The goal is to have -polly-stmt-granularity=bb and -polly-stmt-granularity=scalar-indep to have the same names if there is just one statement per basic block. This fixes a fluke when Polybench's jacobi-2d is optimized differently depending on the -polly-stmt-granularity option, although both options create the same SCoP, just with different statement names. The new naming scheme is: With -polly-use-llvm-names=0: Stmt<BBIdx as decimal><Idx within BB as letter> With -polly-use-llvm-names=1: Stmt_BBName_<Idx within BB as letter> The <Idx within BB> suffix is omitted for the main statement of a BB. The main statement is either the one containing the first store or call (those cannot be removed by the simplifyer), or if there is no such instruction, the first. If after simplification there is just a single statement left, it should be the main statement and have the same names as with -polly-stmt-granularity=bb.
