Add support for the rust offset intrinsic
This patch adds the initial support for generic intrinsics these are do not
map directly to GCC builtins and need to be substited with their specificed
types. This patch allows for custom implementation body for these functions
by specifying handler functions which will generate the applicable
intrinsic when asked for.
