Consistently use a tab rather than a space as the separator between the
assembly instruction mnemonic and its operand with FSFLAGS instructions
produced with the unordered FP comparison RTL insns.
gcc/
* config/riscv/riscv.md
(*f<quiet_pattern>_quiet<ANYF:mode><X:mode>4_default)
(*f<quiet_pattern>_quiet<ANYF:mode><X:mode>4_snan): Emit a tab
rather than space with FSFLAGS.

Hi,
Committed as obvious.
