switch expansion: limit JT growth param values
Currently, one can request a huge jump table creation which
leads to a non-sensual huge output. Moreover, use auto_vec rather
than a stack-allocated array.
PR middle-end/107976
gcc/ChangeLog:
* params.opt: Limit JT params.
* stmt.cc (emit_case_dispatch_table): Use auto_vec.
