[RFC,03/23] AARCH64: Replace regset_alloc() invocations by static regset structures
Commit Message
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.
