[libc-commits] [PATCH] D105843: [libc] Add option to run specific test binaries

caitlyncano requested review of this revision.

This addition reads command line input to run specific single tests
within a larger call to run all the tests for a particular function.
When the user adds a second argument to the command line, the code skips
all the tests that don't match the user's specified binary. If the user
doesn't specify a test correctly and/or no tests are run, a failure
message prints.
