[PATCH] Use proper type in linear transformation in tree-switch-conversion (PR tree-optimization/88753).

[Martin Liška]

Hi.

As seen in the PR, when doing switch convert linear transformation,
one needs to first convert to unsigned type for constructor values.

Patch survives regression tests and bootstrap on x86_64-linux-gnu.
Ready for trunk?
Thanks,
Martin
