[2/9] Encoding support for AArch64 DWARF operations

[Jiong Wang]

The encoding for new added AARCH64 DWARF operations.

I am thinking DWARF specification actually allows vendor private operations
overlap with each other as one can't co-exist with the other.  So in theory we
should introduce target hook to handle target private operations.

But in GCC/binutils/LLVM scope, I only see one overlap between
DW_OP_GNU_push_tls_address and and DW_OP_HP_unknown, and DW_OP_HP_unknown seems
not used.

So I added the support in GCC generic code directly instead of introducing
target hook.

Is this OK to install?

         and DW_OP_AARCH64_paciasp_deref.
