Arm: Add read_description read funcs and use in GDB
Switch the Arm target to get target descriptions via arm_read_description and aarch32_read_description, in the same style as other feature targets. Add an enum to specify the different types - this will also be of use to gdbserver in a later patch. Under the hood return the same existing pre-feature target descriptions. gdb/ChangeLog: * Makefile.in: Add new files. * aarch32-tdep.c: New file. * aarch32-tdep.h: New file. * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Call aarch32_read_description. * arch/aarch32.c: New file. * arch/aarch32.h: New file. * arch/arm.c (arm_create_target_description) (arm_create_mprofile_target_description): New function. * arch/arm.h (arm_fp_type, arm_m_profile_type): New enum. (arm_create_target_description) (arm_create_mprofile_target_description): New declaration. * arm-fbsd-tdep.c (arm_fbsd_read_description_auxv): Call read_description functions. * arm-linux-nat.c (arm_linux_nat_target::read_description): Likewise. * arm-linux-tdep.c (arm_linux_core_read_description): Likewise. * arm-tdep.c (tdesc_arm_list): New variable. (arm_register_g_packet_guesses): Call create description functions. (arm_read_description) (arm_read_mprofile_description): New function. * arm-tdep.h (arm_read_description) (arm_read_mprofile_description): Add declaration. * configure.tgt: Add new files.
