- In the SCF Utils, add the `parallelLoopUnrollByFactors()` function to
unroll scf::ParallelOp loops according to the specified unroll factors
- Add a test pass "TestParallelLoopUnrolling" and the related LIT test
- Expose `mlir::parallelLoopUnrollByFactors()`,
`mlir::generateUnrolledLoop()`, and `mlir::scf::computeUbMinusLb()`
functions in the mlir/Dialect/SCF/Utils/Utils.h and /IR/SCF.h headers to
make them available to other passes.
- In `mlir::generateUnrolledLoop()`, add an optional `IRMapping *clonedToSrcOpsMap`
argument to map the new cloned operations to their
original ones. In the function body, change the default `AnnotateFn`
type to `static const` to silence potential warnings about dangling
references when a function_ref is assigned to a variable with automatic
storage.
