intel/compiler: Add support for bindless shaders

Browse Source 
The Intel bindless thread dispatch model is very simple.  When a compute
shader is to be used for bindless dispatch, it can request a set of
stack IDs.  These are allocated per-dual-subslice by the hardware and
recycled automatically when the stack ID is returned.  Passed to the
bindless dispatch are a global argument address, a stack ID, and an
address of the BINDLESS_SHADER_RECORD to invoke.  When the bindless
shader is dispatched, it is passed its stack ID as well as the global
and local argument pointers.  The local argument pointer is the address
of the BINDLESS_SHADER_RECORD plus some offset which is specified as
part of the BINDLESS_SHADER_RECORD.
