rs6000: Add support for __builtin_cpu_is ("power10")

Browse source 
Add support for __builtin_cpu_is ("power10").  Also add documentation for
the recently added "arch_3_1" and "mma" __builtin_cpu_supports arguments.

2020-06-25  Peter Bergner  <bergner@linux.ibm.com>

gcc/
	* config/rs6000/rs6000-call.c (cpu_is_info) <power10>: New.
	* doc/extend.texi (PowerPC Built-in Functions): Document power10,
	arch_3_1 and mma.

gcc/testsuite/
	* gcc.target/powerpc/cpu-builtin-1.c: Add tests for power10, arch_3_1
	and mma.
