GCN: libgomp+mkoffload.cc: Prepare for reverse offload fn lookup
Add support to GCN for reverse lookup of function name to prepare for
'omp target device(ancestor:1)'.
gcc/ChangeLog:
* config/gcn/mkoffload.cc (process_asm): Create .offload_func_table,
similar to pre-existing .offload_var_table.
libgomp/ChangeLog:
* plugin/plugin-gcn.c (GOMP_OFFLOAD_load_image): Read
.offload_func_table to populate rev_fn_table when requested.
