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.

Summary:
Before, if we fail to parse a jscop file, this will be reported as an
error and importing is aborted. However, this isn't actually strong
enough, since although the import is aborted, the scop has already been
modified and is very likely broken. Instead, make this a hard failure
and throw an LLVM error. This new behaviour requires small changes to
the tests for the legacy pass, namely using `not` to verify the error.
Further, fixed the jscop file for the
base_pointer_load_is_inst_inside_invariant_1 testcase.

Without this patch, the JSONImporter did not verify if the data it loads
were correct or not (Bug llvm.org/PR32543). I add some checks in the
JSONImporter class and some test cases.
Here are the checks (and test cases) I added :
JSONImporter::importContext
- The "context" key does not exist.
- The context was not parsed successfully by ISL.
- The isl_set has the wrong number of parameters.
- The isl_set is not a parameter set.
JSONImporter::importSchedule
- The "statements" key does not exist.
- There is not the right number of statement in the file.
- The "schedule" key does not exist.
- The schedule was not parsed successfully by ISL.
JSONImporter::importAccesses
- The "statements" key does not exist.
- There is not the right number of statement in the file.
- The "accesses" key does not exist.
- There is not the right number of memory accesses in the file.
- The "relation" key does not exist.
- The memory access was not parsed successfully by ISL.
JSONImporter::areArraysEqual
- The "type" key does not exist.
- The "sizes" key does not exist.
- The "name" key does not exist.
JSONImporter::importArrays
/!\ Do not check if there is an key name "arrays" because it is not
considered as an error.
All checks are already in place or implemented in
JSONImporter::areArraysEqual.
