Add a check on run lines to pick up isel options in llc commands and allow generating check lines of isel final output other than assembly. If llc command line contains -debug-only=isel, update_llc_test_checks.py will try to scrub isel output, otherwise, the script will fall back on default behaviour, which is try to scrub assembly output instead.

This patch only implements the initial change to differentiate isel output from assembly output for Lanai. Other targets will not be supported for isel check generation at the moment. Although adding support for it will only require implementing the function regex and scrubber for corresponding targets.

The Lanai implementation was chosen mainly for the simplicity of demonstrating the difference between isel checks and asm checks.

This patch also do not include the implementation of function prefix, which is required for the generated isel checks to pass.
