Add Clearwater Forest.
(processor_alias_table): Ditto.
* common/config/i386/i386-cpuinfo.h (enum processor_types):
Add INTEL_CLEARWATERFOREST.
* config.gcc: Add -march=clearwaterforest.
* config/i386/driver-i386.cc (host_detect_local_cpu): Handle
clearwaterforest.
* config/i386/i386-c.cc (ix86_target_macros_internal): Ditto.
* config/i386/i386-options.cc (processor_cost_table): Ditto.
(m_CLEARWATERFOREST): New.
(m_CORE_ATOM): Add clearwaterforest.
* config/i386/i386.h (enum processor_type): Ditto.
* doc/extend.texi: Ditto.
* doc/invoke.texi: Ditto.
gcc/testsuite/ChangeLog:
