Add DW_CFA_AARCH64_negate_ra_state to dwarf2.def/h and dwarfnames.c
A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for ARMv8.3-A
return address signing, it is multiplexing DW_CFA_GNU_window_save in CFA vendor
extension space.
This patch adds necessary code to make it available to external, the GDB
patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is intended
to use it.
A new DW_CFA_DUP for it is added in dwarf2.def. The use of DW_CFA_DUP is to
avoid duplicated case value issue when included in libiberty/dwarfnames.
Native x86 builds OK to make sure no macro expanding errors.
Committed on behalf of Jiong Wang.
