From: Frédéric Pétrot <frederic.petrot@univ-grenoble-alpes.fr>
Given that the 128-bit version of the riscv spec adds new instructions, and
that some instructions that were previously only available in 64-bit mode
are now available for both 64-bit and 128-bit, we added new macros to check
for the processor mode during translation.
Although RV128 is a superset of RV64, we keep for now the RV64 only tests
for extensions other than RVI and RVM.
