Add linux_get_hwcap
Tidy up calls to read HWCAP (and HWCAP2) by adding common functions, removing the PPC and AArch64 specific versions. The only function difference is in aarch64_linux_core_read_description - if the hwcap read fails it now return a valid description instead of nullptr. gdb/ChangeLog: 2019-03-25 Alan Hayward <alan.hayward@arm.com> * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Call linux_get_hwcap. * aarch64-linux-tdep.c (aarch64_linux_core_read_description): Likewise. (aarch64_linux_get_hwcap): Remove function. * aarch64-linux-tdep.h (aarch64_linux_get_hwcap): Remove declaration. * arm-linux-nat.c (arm_linux_nat_target::read_description):Call linux_get_hwcap. * arm-linux-tdep.c (arm_linux_core_read_description): Likewise. * linux-tdep.c (linux_get_hwcap): Add function. (linux_get_hwcap2): Likewise. * linux-tdep.h (linux_get_hwcap): Add declaration. (linux_get_hwcap2): Likewise. * ppc-linux-nat.c (ppc_linux_get_hwcap): Remove function. (ppc_linux_get_hwcap2): Likewise. (ppc_linux_nat_target::region_ok_for_hw_watchpoint): Call linux_get_hwcap. (ppc_linux_nat_target::insert_watchpoint): Likewise.
