amdgcn: Pass -mstack-size through to runtime
But only for the offload case.
gcc/ChangeLog:
* config/gcn/mkoffload.cc (gcn_stack_size): New global variable.
(process_asm): Create a constructor for GCN_STACK_SIZE.
(main): Parse the -mstack-size option.
(cherry picked from commit 45e01229af33a3dc3f124dcaec4b4ae11e9d07ce)
