Turns out that we do have a test now, as meanwhile Andrew added
gdb.arch/riscv-reg-aliases.exp which tests reading/writing registers
via their aliases, including FP registers, and I'm getting a lot of
failures from this new testcase because my patch conflicts with it.
It doesn't specifically test 32-bit float FP values though, but it
looks easy enough to add that in, or we could maybe use the framework
for a second related testcase.
