919e459f - [Linalg] Remove Optional from getStaticLoopRanges interface method.

[Linalg] Remove Optional from getStaticLoopRanges interface method. It is very wrong if the ranges can't be infered. It's also checked in verifyStructuredOpInterface, so we don't need the Optional return type. Reviewed By: springerm Differential Revision: https://reviews.llvm.org/D124596
