[Patch SRA] Fix PR66119 by calling get_move_ratio in SRA
gcc/
PR tree-optimization/66119
* toplev.c (process_options): Don't set up default values for
the sra_max_scalarization_size_{speed,size} parameters.
* tree-sra (analyze_all_variable_accesses): If no values
have been set for the sra_max_scalarization_size_{speed,size}
parameters, call get_move_ratio to get target defaults.
gcc/testsuite/
PR tree-optimization/66119
* g++.dg/opt/pr66119.C: New.
