[mips] Lift the assertion on the types that can be used with MipsGPRel Post commit review of rL308619 highlighted the need for handling N64 with -fno-pic. Testing reveale a stale assert when generating a GP relative addressing mode. This patch removes that assert and adds the necessary patterns for MIPS64 to perform gp relative addressing with -fno-pic (and the implicit -mno-abicalls + -mgpopt).

; Check that when synthesizing a pointer to the second element of foo, that
; we use the correct addition operation. O32 and N32 have 32-bit address
; spaces, so they use addiu. N64 has a 64bit address space, but has a submode
; where symbol sizes are 32 bits. In those cases we use daddiu.
