ISL 0.16 will change how sets are printed which breaks 117 unit tests
that text-compare printed sets. This patch re-formats most of these unit
tests using a script and small manual editing on top of that. When
actually updating ISL, most work is done by just re-running the script
to adapt to the changed output.
Some tests that compare IR and tests with single CHECK-lines that can be
easily updated manually are not included here.
The re-format script will also be committed afterwards. The per-test
formatter invocation command lines options will not be added in the near
future because it is ad hoc and would overwrite the manual edits.
Ideally it also shouldn't be required anymore because ISL's set printing
has become more stable in 0.16.

Accesses for exit node phis will be handled separately by
buildPHIAccesses if there is more than one exiting edge,
buildScalarDependences does not need to create additional SCALAR
accesses.
This is a corrected version of r250517, which was reverted in r250607.

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 change addresses three issues:
- Read only scalars that enter a PHI node through an edge that comes from
outside the scop are not modeled any more, as such PHI nodes will always
be initialized to this initial value right before the SCoP is entered.
- For PHI nodes that depend on a scalar value that is defined outside the
scop, but where the scalar values is passed through an edge that itself
comes from a BB that is part of the region, we introduce in this basic
block a read of the out-of-scop value to ensure it's value is available
to write it into the PHI alloc location.
- Read only uses of scalars by PHI nodes are ignored in the general read only
handling code, as they are taken care of by the general PHI node modeling
code.
