These flags are now always passed to all tests and need to be disabled if
not needed. Disabling these flags, rather than passing them to almost all
tests, significantly simplfies our RUN: lines.

This moves the construction of ScopStmt to the beginning of the
ScopInfo pass. The late creation was a result of the earlier separation
of ScopInfo and TempScopInfo. This will avoid introducing more
ScopStmt-like maps in future commits. The AccFuncMap will also be
removed in some future commit. DomainMap might also be included into
ScopStmt.
The order in which ScopStmt are created changes and initially creates
empty statements that are removed in a simplification.

This patch allows switch instructions with affine conditions in the
SCoP. Also switch instructions in non-affine subregions are allowed.
Both did not require much changes to the code, though there was some
refactoring needed to integrate them without code duplication.
In the llvm-test suite the number of profitable SCoPs increased from
135 to 139 but more importantly we can handle more benchmarks and user
inputs without preprocessing.
