We can't define FLOAT_STORE_FLAG_VALUE for SSE since we can't
represent 0xfff as a valid FP value. This patch makes
fold_rtx to match simplify_relational_operation:

This is a target bug really since it is SSE which needs to set
FLOAT_STORE_FLAG_VALUE correctly.
In that case, I think simplify-rtx.c:simplify_relational_operation() is being
overly
