[arm] Move cpu and architecture option name parsing

Programming / Compilers / GCC - rearnsha [138bc75d-0d04-0410-961f-82ee72b054a4] - 16 June 2017 17:03 EDT

This patch has no functional change. The code used for parsing -mcpu,
-mtune and -march options is simply moved from arm.c arm-common.c. The list of FPU options is also moved. Subsequent patches will make use of this within the driver.

Some small adjustments are needed as a consequence of moving the definitions of the data objects to another object file, in that we no-longer have direct access to the size of the object.

- common/config/arm/arm-common.c (arm_initialize_isa): Moved here from config/arm/arm.c. (arm_print_hint_for_cpu_option): Likewise. (arm_print_hint_for_arch_option): Likewise. (arm_parse_cpu_option_name): Likewise. (arm_parse_arch_option_name): Likewise.
- config/arm/arm.c (arm_identify_fpu_from_isa): Use the computed number of entries in the all_fpus list.
- config/arm/arm-protos.h (all_architectures, all_cores): Declare. (arm_parse_cpu_option_name): Declare. (arm_parse_arch_option_name): Declare. (arm_parse_option_features): Declare. (arm_intialize_isa): Declare.
- config/arm/parsecpu.awk (gen_data): Move CPU and architecture data tables to ... (gen_comm_data): ... here. Make definitions non-static.
- config/arm/arm-cpu-data.h: Regenerated.
- config/arm/arm-cpu-cdata.h: Regenerated.
