Because unallocated encodings generate different exception syndrome information from traps due to FP being disabled, we can't do a single "is fp access disabled" check at a high level in the decode tree. To help in catching bugs where the access check was forgotten in some code path, we set this flag when the access check is done, and assert that it is set at the point where we actually touch the FP regs. This requires us to pass the DisasContext to the vec_reg_offset and fp_reg_offset functions.
