Added support in FunctionAttrs for adding relevant function/argument attributes for the posix call gettimeofday.
This implies annotating it as nounwind and its arguments as nocapture. To be
conservative, we do not annotate the arguments with noalias since some platforms
do not have restrict on the declaration for gettimeofday.
