GCC maintainers:
The following patch adds tests for two of the rs6000 overloaded built-
ins that do not have tests. Additionally the GCC documentation file
doc/extend.texi is updated to include the built-in definitions as they
were missing.
The patch has been tested on a Power 10 system with no regressions.
Please let me know if this patch is acceptable for mainline.

-------------------------------------------
rs6000, Add missing overloaded bcd builtin tests
The two BCD overloaded built-ins __builtin_bcdsub_ge and __builtin_bcdsub_le
do not have a corresponding test. Add tests to existing test file and update
the documentation with the built-in definitions.
gcc/ChangeLog:
* doc/extend.texi (__builtin_bcdsub_le, __builtin_bcdsub_ge): Add
documentation for the builti-ins.
gcc/testsuite/ChangeLog:
* bcd-3.c (do_sub_ge, do_suble): Add functions to test builtins
__builtin_bcdsub_ge and __builtin_bcdsub_le).
