Arnold Schwaighofer c14380d195 LoopVectorize: Math functions only read rounding mode ...

Math functions are mark as readonly because they read the floating point
rounding mode. Because we don't vectorize loops that would contain function
calls that set the rounding mode it is safe to ignore this memory read.
