Two specific test cases for the i386 target, pr27827.c and pr50038.c, are now compiled with the -mno-sse flag. This change prevents test failures related to SSE instructions that arose after a recent commit allowed for two-lane vector reductions without explicit target support. These tests did not originally rely on SSE instructions.
