ASAN greatly increases the memory footprint of Ruby, so these static
thresholds are not appropriate. There's no real need to run these tests
under ASAN.
[Bug #20274]
The current build system uses runtime dependencies from only
`.bundle` directory. We shouldn't install runtime dependencies
from rubygems.org when `make test-bundled-gems` is invoked.
```
test.rb:1:in 'Object#toplevel_meth': unhandled exception

```
[Feature #19117]
This commit adds `GC.auto_compact = :empty` which will run
auto-compaction sorting pages by empty slots so the most amount of
objects will be moved. This will make it easier to write tests for
auto-compaction.

* Provide a new API compile_file_prism which mirrors compile_file
but uses prism to parse/compile.
* Provide the ability to run test-all with RUBY_ISEQ_DUMP_DEBUG set
to "prism". If it is, we'll use the new compile_file_prism API to
load iseqs during the test run.
test/runner.rb and tool/lib/test/unit/parallel.rb must use the same
settings. However, some settings were copied and pasted, while some were
added only to test/runner.rb.
This changeset creates tool/test/init.rb for all settings of test-unit,
which is loaded not only by test/runner.rb but also
tool/lib/test/unit/parallel.rb.
Background: the GEM_HOME environment variable was removed in
test/runner.rb, which prohibit `require "rake"` (note that rake is a
bundled gem). However the parallel mode didn't refrect this setting,
i.e., `require "rake"` was allowed.
This leads to an inconsistency, which actually affected a test test
defines s test class *only when* `require "rake"` is successful.

@passed is redefined in a few test suites, and this could lead to bugs.
Also rename @options (Runner#options) to @__runner_options__, which is
only used in make test-tool anyway.
