Henry Robinson 635dd7d289 IMPALA-875: Respect isAnalyzed_ in IntLiteral expressions ...

Partition column expressions are analysed twice for INSERT statements -
once to infer the type and so to add a possible cast, and once to
compute stats on the resulting expr. However, this process resulted in
an partition column expr that was a IntLiteral getting the smallest type
that would contains its value, rather than retaining the
column-compatible type that had been assigned to it.

This patch does the minimum thing, which is make IntLiteral.analyze()
idempotent. Doing the same thing to Expr and LiteralExpr unearths some
other bugs, which we will have to fix in a follow-on patch (see
IMPALA-884).
