util: try to use SSE instructions with MSVC and 32-bit gcc
The lrint() and lrintf() functions are pretty slow and make some
texture transfers very inefficient. This patch makes a better effort
at using those intrisics for 32-bit gcc and MSVC.
Note, this patch doesn't address the use of SSE4.1 with MSVC.
v2: get rid of the ROUND_WITH_SSE symbol, per Matt.
