From: WANG Rui <wang...@loongson.cn> The BCEQZ and BCNEZ instructions depend on access to condition codes from floating-point comparisons. Previously, these instructions were unconditionally enabled for 64-bit targets.
This patch updates their translation to be gated under the `FP` feature flag instead, ensuring they are only available when the floating-point unit is present. This improves correctness for CPUs lacking floating-point support.
