ARMv8.2 is an architectural extension of ARMv8. This patch adds an
architecture feature macro for ARMv8.2 to the binutils AArch64 target
with GAS command line option -march=armv8.2-a.

Nowadays aarch64_decode_insn is a public interface used by both
opcodes and gdb. However, its behaviour relies on a global variable
no_aliases, which isn't a good practise. On the other hand, In default,
no_aliases is zero, but in GDB, we do want no alias when decoding
instructions for prologue analysis (patches to be posted), so that we
can handle both instructions "add" and "mov" (an alias of "add") as
"add". The code in GDB can be simplified.
This patch adds a new argument in aarch64_decode_insn, and pass no_aliases
to it. In GDB side, always pass 1 to it.

'template' is used in include/opcode/aarch64.h as below,
typedef struct
{
const char *template;
uint32_t value;
int has_xt;
} aarch64_sys_ins_reg;
and it triggers compilation errors when GDB is built in C++ mode.
In file included from git/gdb/aarch64-tdep.c:62:0:
git/gdb/../include/opcode/aarch64.h:651:15: error: expected unqualified-id before 'template'

This patch is to rename field template to name.

We want to use disas_aarch64_insn inside GDB to decode instructions, so
this patch exposes it and rename it to aarch64_decode_insn to follow
the conventions of other interfaces.

The ARMv8.1 architecture introduced the Privileged Access Never extension. This
adds a processor state field PSTATE.PAN which can be accessed using the MRS/MSR
instructions.
This patch adds support for the PAN architecture feature and processor state
field to libopcode.
