[Bug target/42040] New: [ia64] Inappropriate address spills

Looking at msmpeg4.s from PR 41567, build with -O2 -fPIC, we see


.LC2:
        data8   mv_tables#+72
...
        addl r14 = @gprel(.LC2), gp

We should not have spilled that address to the constant pool.

Add -mno-sdata and it gets worse -- LC2 moves from .sdata to
the .data.rel.ro section but we *still* use @gprel to address
it, and that relocation may well be out of range.
