MCOL-4188 Fix regressions in CEIL()/CHAR() for narrow decimals.

Browse Source 
In addition, a regression in a WHERE clause with a WF field
as the LHS and an addition operation on two WF fields on the RHS
is also fixed. The issue was SimpleColumn::getDecimalVal() was
setting precision = 19, with the value of one of the operands of the
addition operation being set in VDecimal::value instead of
VDecimal::s128Value. addSubtractExecute() in mcs_decimal.cpp makes the
assumption that if precision > 18 and precision <= 38, we need to
fetch the wide s128Value, not the narrow value field. So we are
fixing the precision set in SimpleColumn::getDecimalVal().
