[v2] gdb/testsuite/gdb.rocm: Check value returned by hipDeviceSynchronize
Checks
Commit Message
Functions of the hip runtime returning a hipError_t can be marked
nodiscard depending on the configuration[1] (when compiled with C++17).
This patch makes sure that we always check value returned by
hipDeviceSynchronize and friends, and print an error message when appropriate.
This avoid a wall of warnings when running the testsuite if the compiler
defaults to using C++17.
It is always a good practice to check the return values anyway.

Change-Id: I2a819a8ac45f4bcf814efe9a2ff12c6a7ad22f97
---
Changes since V1:
- Improved the commit message,
- Check the return value in gdb/testsuite/lib/rocm.exp
(allow_hipcc_tests) as well.
