parse negative numbers into one item
use Item->neg to convert generate negative Item_num's
instead of Item_func_neg(Item_num).
Based on the following commit:

Make negative number their own token
The negation (-) operator will call Item->neg() one underlying numeric constants
and remove itself (like the NOT() function does today for other NOT functions.
This simplifies things
- -1 is not anymore an expression but a basic_const_item
- improves optimizer
- DEFAULT -1 doesn't need special handling anymore
- When we add DEFAULT expressions, -1 will be treated exactly like 1
- printing of items doesn't anymore put braces around all negative numbers
Other things fixed:
- Fixed that longlong converted to decimal's has a more appropriate size
- Fixed that "-0.0" read into a decimal is interpreted as 0.0
