History
David Benjamin 4616bb1e6e Build 32-bit assembly with SSE2 enabled. 
This affects bignum and sha. Also now that we're passing the SSE2 flag, revert
the change to ghash-x86.pl which unconditionally sets $sse2, just to minimize
upstream divergence. Chromium assumes SSE2 support, so relying on it is okay.
See https://crbug.com/349320.

Note: this change needs to be mirrored in Chromium to take.
