* common.opt (lto_partition_model): New enum.
(flto-partition=): Merge separate options with a single with argument,
add -flto-partition=one support.
* flag-types.h (enum lto_partition_model): Declare.
* opts.c (finish_options): Remove duplicate -flto-partition=
option check.
* lto-wrapper.c (run_gcc): Adjust.
lto/
* lto.c: Include params.h.
(do_whole_program_analysis): Switch on flag_lto_partition value,
add support for LTO_PARTITION_ONE.
* lto-partition.h (lto_balanced_map): Adjust.
* lto-partition.c (lto_balanced_map): Get number of desired
partitions as argument to support -flto-partition=one.
