cefc58c1 - [lit] Add --check to run only selected RUN lines from a test

[lit] Add --check to run only selected RUN lines from a test `llvm-lit --check=LIST <test>` keeps only the listed RUN directives in the test and discards the rest. LIST is a comma-separated mix of 0-indexed integers and ranges (e.g. `--check=0,2,4-6`). The selection is applied to the parseIntegratedTestScript output. Run tests via `llvm-lit --check=0 llvm/utils/lit/tests/Inputs/check-filter/sample.ll`, `llvm-lit --check=1 llvm/utils/lit/tests/Inputs/check-filter/sample.ll`, `llvm/utils/lit/lit.py llvm/utils/lit/tests/check-filter.py`.
