i386: move alignment defaults to processor_costs.
2018-09-17 Martin Liska <mliska@suse.cz>
* common/config/i386/i386-common.c (ix86_get_valid_option_values):
Use processor_names table.
* config/i386/i386.c (ix86_default_align): Use
processor_cost_table for alignment values.
(ix86_option_override_internal): Use processor_names.
(ix86_function_specific_print): Likewise.
* config/i386/i386.h (struct processor_costs):
Add alignment values.
(struct ptt): Remove and replace with const char *.
* config/i386/x86-tune-costs.h (struct processor_costs):
Declare default alignments for all costs.
