While there, turn it from an array of two 32-bit ints into a properly aligned 64-bit int. Use of OPENSSL_ia32_P is now restricted to the assembler parts. C code will now always use OPENSSL_cpu_caps() and check for the proper bits in the whole 64-bit word it returns. i386 tests and ok jsing@

| | | | | | | | | | | | | | | | | | | code for improved readability, however it also address two issues. The first of these is a hard-to-hit double free that will occur if EVP_DigestInit_ex() fails. To avoid this and to be more robust, ensure that tls1_digest_cached_records() either completes successfully and sets up all of the necessary digests, or it cleans up and frees everything that was allocated. The second issue is that EVP_DigestUpdate() can fail - detect and handle this in tls1_finish_mac() and change the return type to an int so that a failure can be propagated to the caller (the callers still need to be fixed to handle this, in a later diff). The double-free was reported by Matthew Dillon. ok beck@ doug@ miod@
