[RISCV] Allow access to FP CSRs without F extension
Summary:
Floating-point CSRs should be accessible even when F extension is not enabled.
But pseudo instructions that access floating point CSRs still require the F extension.
GNU tools already implement this behavior. RISC-V spec is pending update to reflect
this behavior and to extend it to pseudo instructions that access floating point CSRs.
