[PATCH 1/4] [Cleanup] x86: signal: unify the sigaltstack check with other arches

Currently x86's get_sigframe() checks for "current->sas_ss_size" to determine whether there is a need to switch to sigaltstack. The common practice used by all other arches is to check for sas_ss_flags(sp) == 0 This patch makes the code consistent with other arches. The slight complexity of the pa
