Support running dalvikvm under gdb on host.

Supports debugging dalvikvm on host (host & simulator modes);
adds '--gdb' CLI option.

Also adds a check that debugging is only enabled for run-tests
as gtests are not yet supported by ./art scripts.

Note: --gdb and --gdb-dex2oat could be used together.

Test: ./scripts/tests/test_art_host.sh --64bit --gdb
      --single-test 530-checker-peel-unroll
Test: ./scripts/tests/test_art_host.sh --64bit --gdb --gdb-dex2oat
      --single-test 530-checker-peel-unroll
Test: ./scripts/tests/test_art_simulator.sh --gdb
      --single-test 530-checker-peel-unroll
