Convert tests/run-make/instrument-coverage to an ordinary codegen test
This test was already very close to being an ordinary codegen test, except that it needed some extra logic to set a few variables based on (target) platform characteristics. Now that we have support for `//@ filecheck-flags:`, we can instead set those variables using the normal test revisions mechanism.
