Replaces use of aarch64_type_align with common type_align function. Doing this fixes a bug in aarch64_type_align where static fields are considered as part of the alignment calculation of a struct, which results in arguments passed on the stack being misaligned. This bug is exposed in the new test gdb.cp/many-args.exp. Part of the old aarch64_type_align is retained and used as the gdbarch type align callback in order to correctly align vectors. gdb/ChangeLog: * aarch64-tdep.c (aarch64_type_align): Only handle vector override case. (pass_on_stack): Use type_align. (aarch64_gdbarch_init): Register aarch64_type_align gdbarch function. gdb/testsuite/ChangeLog: * gdb.cp/many-args.cc: New file. * gdb.cp/many-args.exp: New file.
