Return X86_XSTATE_SSE_MASK instead of 0 in i386fbsd_core_read_xcr0
i386fbsd_core_read_xcr0 reads the value of xcr0 from the corefile. If it fails, returns 0. This makes its caller {i386,amd64}_target_description has to handle this special value. IMO, i386fbsd_core_read_xcr0 should return the default xcr0 in case of error. gdb: 2017-09-04 Yao Qi <yao.qi@linaro.org> * i386-fbsd-tdep.c (i386fbsd_core_read_xcr0): Return X86_XSTATE_SSE_MASK instead of 0.
