Elena Demikhovsky 092858588a Scalarizer for masked.gather and masked.scatter intrinsics. ...

When the target does not support these intrinsics they should be converted to a chain of scalar load or store operations.
If the mask is not constant, the scalarizer will build a chain of conditional basic blocks.
I added isLegalMaskedGather() isLegalMaskedScatter() APIs.
