-This patch deletes the code that disallows -mprefixed and -mcmodel=large. By
-deleting the code, it allows the normal pc-relative addressing to be used. For
-static variables, pc-relative addressing will be used. For external variables,
-we will generate the normal code that uses '@got@pcrel' addressing to load up
-the external address and use this address as a pointer to do the load or store.
