IBM Z: Support vector _Bool language extension
_Bool needs to be defined as macro in order to trigger the
context-sensitive macro expansion mechanism.
gcc/ChangeLog:
* config/s390/s390-c.c (s390_cpu_cpp_builtins_internal): Define
_Bool as macro expanding to _Bool.
gcc/testsuite/ChangeLog:
* gcc.target/s390/zvector/vec-_Bool.c: New test.
