opcodes: support insn endianness in cgen_cpu_open
This patch adds support for a new CGEN_OPEN_INSN_ENDIAN argument
for @arch@_cgen_cpu_open. This is useful for architectures in
which the endianness of the instruction words is not the same
than the endianness used for data.
An accompanying patch has been sent to the CGEN mailing list that
adds support for this argument on the CGEN side [1]. Its been
already pre-approved [2], and will be applied simultaneously with
this binutils series.
