This patch adds a test scaffold for OpenMP compile tests in under the gcc.target
testsuite. It also adds a target tests directory libgomp.target along with an
SVE execution test
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/sve/omp/gomp.exp: New scaffold.
libgomp/ChangeLog:
* testsuite/libgomp.target/aarch64/aarch64.exp: New scaffold.
* testsuite/libgomp.target/aarch64/shared.c: New test.
