Allow Targets in Test Cases (#229)

* Add an optional `targets` field to cases.

This PR adds an optional `targets` field to cases which takes presence
over that same field in the `Metadata`. The hope from this is to allow
us to limit specific tests so that they only run on specific platforms
only.

* Update the resolc tests submodule

* Update the default resolc version to use

* Update the default heap-size and stack-size in the cli

* Update the report processor
