[HIP] Add option -fgpu-allow-device-init
Add this option to allow device side class type global variables
with non-trivial ctor/dtor. device side init/fini functions will
be emitted, which will be executed by HIP runtime when
the fat binary is loaded/unloaded.
This feature is to facilitate implementation of device side
sanitizer which requires global vars with non-trival ctors.
By default this option is disabled.
