Revert "[SchedBoundary] Add dump method for resource usage."

Reverting because of https://lab.llvm.org/buildbot#builders/16/builds/41860

When building on x86, I need to specify also -mtriple in the
invocation of llc otherwise the folllowing error shows up:

    'cortex-a55' is not a recognized processor for this target (ignoring processor)

This reverts commit b39a9a94f420a25a239ae03097c255900cbd660e.
