When running LLDB API tests, a user can override test arguments with the
LLDB_TEST_USER_ARGS. However, these flags used to be concatenated with a
CMake-derived variable LLDB_TEST_COMMON_ARGS, as below:
set(LLDB_DOTEST_ARGS ${LLDB_TEST_COMMON_ARGS};${LLDB_TEST_USER_ARGS}
This is problematic, because LLDB_TEST_COMMON_ARGS must be processed
first, while LLDB_TEST_USER_ARGS args must be processed last, so that
user overrides are respected. Currently, if a user attempts to override
one of the "inferred" flags, the user's request is ignored. This is the
case, for example, with `--libcxx-include-dir` and
`--libcxx-library-dir`. Both flags are needed by the greendragon bots.
This commit removes the concatenation above, keeping the two original
variables throughout the entire flow, processing the user's flag last.
This was tested locally by invoking CMake with:
-DLLDB_TEST_USER_ARGS="--libcxx-include-dir=blah --libcxx-library-dir=blah2"
and checking that tests failed appropriately.
