Henrik RydgårdandClaude Opus 5.5 ae32504fa1 RISC-V emitter: Fix Zcb byte offsets, and FLI of a NaN ...

c.lbu and c.sb keep the offset's bit 0 in bit 6 and bit 1 in bit 5, so
offsets 1 and 2 were swapped, and the JIT loaded and stored the wrong byte.

FLI's only NaN is the canonical one, but CanFLI took any NaN for it: the
pattern went through a float to double conversion that quieted it, which on
RISC-V also drops the sign and payload. vfim of a NaN lost its sign.

Neither is detected on real hardware yet (we never set Zcb or Zfa), and the
CPU fuzzer found both with the extensions forced on under qemu.
