[vector] RFR (M): Ensure intrinsics are parameterized with non-capturing lambdas

[Vladimir Ivanov]

Default implementations are implemented as lambdas and capturing 
introduces problems for EA and even if intrinsification happens may 
leave unused objects behind.

The patch:

  * introduces an adhoc check (VectorIntrinsics.isNonCapturingLambda()) 
and asserts all default implementations satisfy it;

  * instruments existing tests to run with assertions enabled;

  * fixes all occurrences of capturing lambdas in the code (so test 
results are clean).

Best regards,
Vladimir Ivanov
