Add more location aliasing checks

When location aliasing, the aliases sharing the location must have the same underlying numerical type and bit width (floating-point or integer, 32-bit versus 64-bit, etc.) and the same auxiliary storage and interpolation qualification.
This adds checks for the "patch" and "sample" qualifiers, and also relaxes the checks when the signedness of integer types differs.
