The `run-tests.py` test execution harness validates the correctness
of JerryScript by building various configurations of jerry and
running various test suites and subsets against it. However, until
now, it always built jerry for each (build configuration, test suite)
pair. This commit improves `run-tests.py` by skipping duplicate
builds, sharing the same-built binaries across multiple test suite
runs.
The patch also improves on the style of how `Option`s are specified
and fixes the name of the `jerry_tests-debug-cpointer_32bit`
option.
