Yes, considering only Shell tests. By default, host testing is assumed. LLDB_TEST_PLATFORM_NAME/LLDB_TEST_PLATFORM_URL must be set to execute remote API&Shell testing. LLDB_SHELL_TESTS_DISABLE_REMOTE may be used to disable it for Shell tests.

Technically, yes. But I think Shell tests don't aim to test a cross-compiler. It's more like "if the cross-compiler is used, that is not compatible with Shell tests, we can run them only on the host to check at least the part of the functionality". It may make sense since only one-fifth of Shell tests run something remotely.
