[PATCH 39/76] target/arm: Handle FPCR.NEP for BFCVT scalar

Currently we implement BFCVT scalar via do_fp1_scalar(). This works even though BFCVT is a narrowing operation from 32 to 16 bits, because we can use write_fp_sreg() for float16. However, FPCR.NEP support requires that we use write_fp_hreg_merging() for float16 outputs, so we can't continue to bor
