gcc: Add CT_CC_GCC_TM_CLONE_REGISTRY config
This commit adds a new gcc config `CT_CC_GCC_TM_CLONE_REGISTRY` that enables the GCC transactional memory clone registry feature for libgcc. Note that the gcc option to control this feature is only available in gcc 10 and above. (see gcc commit 5a4602805eb3ebddbc935b102481e63bffc7c5e6) Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
