I recently upgraded my host compiler to GCC 6.1.0 and while trying to build a
cross toolchain for arm-none-eabi I've encountered some -Werror errors in tc-arm.c
This patch fixes them.
Some static const variables that are unused are marked with ATTRIBUTE_UNUSED.
In parse_neon_el_struct_list GCC complains that firsttype.index may be used
uninitialized in an inlined neon_alias_types_same call.
This patch initialises the fields firsttype to prevent that.
With this patch the gas build succeeds for me.
Tested with make check-gas for arm-none-eabi.
Ok to commit?

* config/tc-arm.c (fpu_arch_vfp_v1): Mark with ATTRIBUTE_UNUSED.
(parse_neon_el_struct_list): Initialize fields of firsttype.
