GCN: Properly switch sections in 'gcn_hsa_declare_function_name' [PR119737]

There are GCN/C++ target as well as offloading codes, where the hard-coded
section names in 'gcn_hsa_declare_function_name' do not fit, and assembly thus
fails:

    LLVM ERROR: Size expression must be absolute.

This commit progresses GCN target:

    [-FAIL: g++.dg/init/call1.C  -std=gnu++17 (internal compiler error: Aborted signal terminated program as)-]
    [-FAIL:-]{+PASS:+} g++.dg/init/call1.C  -std=gnu++17 (test for excess errors)
