gcc/testsuite/s390: Add test cases for float_t
Add two test cases that check for acceptable combinations of float_t and
FLT_EVAL_METHOD on s390x.
Tested against an as-is glibc and one modified so that it derives
float_t from FLT_EVAL_METHOD.
gcc/testsuite/ChangeLog:

* gcc.target/s390/float_t-1.c: New test.
* gcc.target/s390/float_t-2.c: New test.
