Juergen Ributzka b62ac80e67 [ConstantHoisting][X86] Change the cost model to never hoist constants for types larger than i128. ...

Currently the X86 backend doesn't support types larger than i128 very well. For
example an i192 multiply will assert in codegen when the 2nd argument is a constant and the constant got hoisted.

This fix changes the cost model to never hoist constants for types larger than
i128. Once the codegen issues have been resolved, the cost model can be updated
to allow also larger types.
