[tvOS] Failing System.Numerics.Vectors.Tests

[simonrozsival]

Architecture: arm64
Configuration: Release

Some System.Numerics.Tests.GenericVectorTests are failing on tvOS:

• MultiplicationWithScalarSByte
• MultiplicationWithScalarInt16
• MultiplicationWithScalarInt32
• MultiplicationWithScalarInt64
• MultiplicationWithScalarByte
• MultiplicationWithScalarUInt16
• MultiplicationWithScalarUInt32
• MultiplicationWithScalarUInt64
• MultiplicationWithScalarSingle
• MultiplicationWithScalarDouble

The tests fail because the result of multiplication is 0. Sample test output:

Assert.Equal() Failure
Expected: -1981376615
Actual:   0
