Set some fast math attributes in setFunctionAttributes
This will provide a more consistent view to codegen for these
attributes. The current system is somewhat awkward, and the fields in
TargetOptions are reset based on the command line flag if the attribute
isn't set. By forcing these attributes with the flag, there can never be
an inconsistency in the behavior if code directly inspects the attribute
on the function without considering the command line flags.
