[SPARK-17013][SQL] Parse negative numeric literals
## What changes were proposed in this pull request?
This patch updates the SQL parser to parse negative numeric literals as
numeric literals, instead of unary minus of positive literals.
This allows the parser to parse the minimal value for each data type, e.g.
"-32768S".
## How was this patch tested?
Updated test cases.
