IR is now always parsed in opaque pointer mode, unless
-opaque-pointers=0 is explicitly given. There is no automatic
detection of typed pointers anymore.
The -opaque-pointers=0 option is added to any remaining IR tests
that haven't been migrated yet.
Differential Revision: https://reviews.llvm.org/D141912
To avoid overflows we still use a larger type (i64) while calculating the value
of the old ivs. However, we truncate the result to the type of the old iv when
providing it to the new code.
A corresponding test case is added to the polly test suite. Also, a failing test
case is fixed.
This fixes PR12311.

This also adds support for modifiable write accesses (until now only read
accesses where supported). We currently do not derive an exact type for the
expression, but assume that i64 is good enough. This will be improved in future
patches.
