Juan Manuel Martinez Caamaño beae0e9f1a [AMDGPU] Use a target feature to enable __builtin_amdgcn_global_load_lds on gfx9/10 (#133055) ...

This patch introduces the `vmem-to-lds-load-insts` target feature, which
can be used to enable builtins `__builtin_amdgcn_global_load_lds` and
`__builtin_amdgcn_raw_ptr_buffer_load_lds` on platforms which have this
feature.

This feature is only available on gfx9/10.

A limitation of using a common target feature for both builtins is that
we could have made `__builtin_amdgcn_raw_ptr_buffer_load_lds` available
on gfx6,7,8.
