[Patchv3] Control SRA and IPA-SRA by a param rather than MOVE_RATIO
gcc/
* params.def (sra-max-scalarization-size-Ospeed): New.
(sra-max-scalarization-size-Osize): Likewise.
* doc/invoke.texi (sra-max-scalarization-size-Ospeed): Document.
(sra-max-scalarization-size-Osize): Likewise.
* toplev.c (process_options): Set default values for new
parameters.
* tree-sra.c (analyze_all_variable_accesses): Use new parameters.
* targhooks.c (get_move_ratio): Remove static designator.
* target.h (get_move_ratio): Declare.
