Review request for KDevelop and Olivier Jean de Gaalon.


Description
-------

Only compile-time integral constants are valid in "case ..."
statements, so filter any certainly non-constant completion items.

This has 2 usability issues (well, not issues, but questionable points):
1) We do not filter type-names since they can be used either as scopes
(SomeType::someConstant) or as ctor-like initializers
(SomeIntegralTypedef(42)).
2) We do not filter integer-returning functions since they
can be constexpr (thus syntactically usable) but we cannot handle
constexpr now.

But, since one rarely would use these items, their match quality
is forced to zero in order to avoid pollution of "best matches".

Testing
-------

Unit-tests have been made aware of the newly-introduced filtering; usability has been discussed with Olivier Jean de Gaalon.


Thanks,
