AVX-512: Changed lowering of BITCAST between i1 vectors and i8/i16/i32 integer values

[delena]

Summary

Optimized lowering of BITCAST node. The BITCAST node can be replaced with COPY_TO_REG instead of KMOV.
It allows to suppress two opposite BITCAST operations and avoid redundant "movs".

[delena]

removed irrelevant BITCAST patterns

do we need target predicate here ( the same above) ? I think that after the change it can be removed.
