PR tree-optimization/48809
* tree-switch-conversion.c (build_arrays): Compute tidx in unsigned
type.
(gen_inbound_check): Don't compute index_expr - range_min in utype
again, instead reuse SSA_NAME initialized in build_arrays.
Remove two useless gsi_for_stmt calls.
* gcc.c-torture/execute/pr48809.c: New test.
