Make handling of match contexts stricter
beam_validator could fail issue a diagnostic when a register
that was supposed to be a match context was not guaranteed to
be a match context.
The bug was in merging of types. Merging of a match context with
another term would result in a match context. That is wrong. Merging
should produce a more general type, not a narrower type. Also, the
valid slots in two match contexts should be combined with 'band', not
'bor'.
