  After removal of the regset_alloc invocations, the tdep fields
'gregset' and 'fpregset' become obsolete and are thus removed.

gdb/
	* aarch64-linux-tdep.c (aarch64_linux_gregset)
	(aarch64_linux_fpregset): New static regset structures.
	(aarch64_linux_regset_from_core_section): Drop dynamic allocation
	of regset structures.
	* aarch64-tdep.h (struct gdbarch_tdep): Remove 'gregset' and
	'fpregset' fields.
