Make OPENSSL_IA32_SSE2 the default for i386 and remove the flag.
The OPENSSL_IA32_SSE2 flag controls whether a number of the perlasm
scripts generate additional implementations that use SSE2 functionality.
In all cases except ghash, the code checks OPENSSL_ia32cap_P for SSE2
support, before trying to run SSE2 code. For ghash it generates a CLMUL
based implementation in addition to different MMX version (one MMX
version hides behind OPENSSL_IA32_SSE2, the other does not), however this
does not appear to actually use SSE2. We also disable AES-NI on i386 if
OPENSSL_IA32_SSE2.
On OpenBSD, we've always defined OPENSSL_IA32_SSE2 so this is effectively
a no-op. The only change is that we now check MMX rather than SSE2 for the
ghash MMX implementation.
