gimple: Don't warn about using different algs for big switch lowering
[PR117091]
We currently don't switch to a faster switch lowering algorithm when a
switch is too big. This patch removes a warning about this.
PR middle-end/117091
gcc/ChangeLog:
* tree-switch-conversion.cc
(switch_decision_tree::analyze_switch_statement):
Remove warning about using different algorithms.
