[PATCH 1/2] gas: RISC-V: Add a test for near->far branch conversion

[Palmer Dabbelt]

This works in GAS and has for a very long time, but I couldn't find a
test case for it.  It doesn't appear to be documented anywhere, but GCC
depends on it and I'd bet a bunch of handwritten assembly does too so
it's probably too late to drop.
