gdb/riscv: Improve flen length determination
This solves an assertion failure when a remote provides a target description which only refers to floating point registers by their hardware name (e.g. f0), rather than their ABI name (e.g. ft0). GDB assumed that should the floating point register feature be presented, it would contain a register called ft0. The floating point length is now instead determined by searching for the same register, but looking for any of its aliases. gdb/ChangeLog: * riscv-tdep.c (riscv_gdbarch_init): Support determining flen from target descriptions using exclusively floating point register name aliases.
