soft-fp quad.h patch

- Subject: soft-fp quad.h patch
This patch fixes soft-fp's quad.h for the case where two unsigned long
long words are being used but unsigned long is only 32 bits (as in MIPS64
N32). (This is needed for a separate patch I'll send to libc-ports to
implement sqrtl for MIPS64. It would probably be safe to change all such
bit-fields to _FP_W_TYPE but only these ones need changing for this
particular use and I haven't tested changing the others.)

* soft-fp/quad.h (_FP_UNION_Q): Use _FP_W_TYPE for frac
bit-fields.
