sdesmalen added a child revision: D77593: [SveEmitter] Implement zeroing of false lanes.

Builtins that have the merge type MergeAnyExp or MergeZeroExp,
merge into a 'undef' or 'zero' vector respectively, which enables the
_x and _z behaviour for unary operations.

      

This patch also adds builtins for svabs and svneg.
