aarch64: Fix up RTL sharing bug in aarch64_load_symref_appropriately [PR104910]
We unshare all RTL created during expansion, but when
aarch64_load_symref_appropriately is called after expansion like in the
following testcases, we use imm in both HIGH and LO_SUM operands.
If imm is some RTL that shouldn't be shared like a non-sharable CONST,
we get at least with --enable-checking=rtl a checking ICE, otherwise might
just get silently wrong code.
The following patch fixes that by copying it if it can't be shared.
