Add --disable-tm-clone-registry libgcc configure option.
This patch adds libgcc configuration option to disable TM clone
registry. This option helps to reduce code size for embedded targets
which do not need transactional memory support.
gcc/
* doc/install.texi: Document --disable-tm-clone-registry.
libgcc/
* Makefile.in (USE_TM_CLONE_REGISTRY): New.
(CRTSTUFF_CFLAGS): Use USE_TM_CLONE_REGISTRY.
* configure.ac: Add --disable-tm-clone-registry option.
* configure: Regenerate.
