[mlir] fix test failure in EDSC/builder-api-test

[inouehrs]

Summary

This patch fixes a test failure on a non-intel (PowerPC64) box.
The two affine.load are independent and hence llvm may reorder them.
The CHECK lines are modified for supporting reordered case.

Please capture the names of SSA values in their definition place instead of using them directly. E.g.,

CHECK-LABEL: func @indirect_access
CHECK-SAME: (%[[A:.*]], %[[B:.*]], ...
CHECK-DAG: [[loadedB:%.*]] = affine.load %[[B]]
