[FRG-41] return type inference (leastRestrictiveTypes) inconsistent with Fennel codegen

[dynamobi-build]

[reporter="jpham", created="Wed, 15 Feb 2006 11:36:19 -0500 (GMT-05:00)"] farrago test case:
create table a_decimal (d decimal(14,4) primary key);
insert into a_decimal values (cast (10 as real));

the optimizer produces a multiplication:
(REAL) * (BIGINT) = (DOUBLE)

the translator for fennel calc generates:
(REAL) * cast( BIGINT as REAL ) = DOUBLE

which is not supported by the fennel calculator
