x86: Update -mtune=intel for Diamond Rapids/Clearwater Forest
-mtune=intel is used to generate a single binary to run well on both big
core and small core, similar to hybrid CPUs. Update -mtune=intel to tune
for Diamond Rapids and Clearwater Forest, instead of Silvermont.
PR target/120815
* common/config/i386/i386-common.cc (processor_alias_table):
Replace CPU_SLM/PTA_NEHALEM with CPU_HASWELL/PTA_HASWELL for
PROCESSOR_INTEL.
* config/i386/i386-options.cc (processor_cost_table): Replace
intel_cost with alderlake_cost.
* config/i386/x86-tune-costs.h (intel_cost): Removed.
* config/i386/x86-tune-sched.cc (ix86_issue_rate): Treat
PROCESSOR_INTEL like PROCESSOR_ALDERLAKE.
(ix86_adjust_cost): Likewise.
* doc/invoke.texi: Update -mtune=intel for Diamond Rapids and
Clearwater Forest.
