Add -march=ia to x86 backend
* config.gcc: Support --with-cpu=ia.
* config/i386/i386.c (cpu_names): Add "ia".
(processor_alias_table): Likewise.
(ix86_option_override_internal): Disallow -march=ia.
* config/i386/i386.h (target_cpu_default): Add
TARGET_CPU_DEFAULT_ia.
* doc/invoke.texi: Document -mtune=ia.
