[nvptx] Improve gcc.target/nvptx/atomic_fetch-*.c test-cases
Fix a few issues in test-cases gcc.target/nvptx/atomic_fetch-*.c: - atomic_fetch-1.c uses scan-assembler instead of scan-assembler-times, which is less accurate - atomic_fetch-2.c only contains negative testing using scan-assembler-not - the test-cases use stack variables to generate generic addresses, while stack atomics are not natively supported - the test-cases only test (64-bit) x (generic), instead of (32-bit, 64-bit) x (generic, global, shared) - the test-cases use a hardcoded '0' instead of the clearer MEMMODEL_RELAXED Tested on nvptx. gcc/testsuite/ChangeLog: 2022-01-12 Tom de Vries <tdevries@suse.de> * gcc.target/nvptx/atomic_fetch-1.c: Rewrite. * gcc.target/nvptx/atomic_fetch-2.c: Rewrite.
