Extend test_runner VMOptions support with an ability to specify
paths relative to temporary compilation directory.
// VMOptions=--foo=$TEST_COMPILATION_DIR/foo.file
The same directory will also be passed as an environment variable
to execution command.
Migrate most of the tests which used to write stuff into the SDK
root to use this feature. I am leaving vm/dart/causal/* tests
unmigrated because migrating requires time consuming manual
update of expectations (which encode raw line numbers). I have
a follow up CL which changes how these tests are written which
will make migration trivial.
