Support single number datetime/date/time parsing

[Shylock-Hg]

Introduction

In function calling as bellow:

date('2019')
datetime('2020')

In current, we only parse the string '2019' and '2020', so parser can't determine the deduce rule and lead to confliction for losing the information. So we could insert the function call information back to the raw string to fix it.
e.g. date('2019') we parse '2019' now, could change to parse '__date2019'.
