That should work.

I had to use ".option norvc" for the libffi risc-v static trampoline
support [1] so that the "jr t2" in the commit wouldn't be automatically
converted to c.jr, so yeah we have to be concerned by more than just
nop.

I'll also note gas and LLVM's assembler don't always agree when to convert
an instruction to the compressed form when it is possible.  Maybe different
defaults within the assemblers?
