re PR target/79041 (aarch64 backend emits R_AARCH64_ADR_PREL_PG_HI21 relocation despite -mpc-relative-literal-loads option being used)
Fix PR79041
As described in PR79041, -mcmodel=large -mpc-relative-literal-loads
may be used to avoid generating ADRP/ADD or ADRP/LDR. However both
trunk and GCC7 may still emit ADRP for some constant pool literals.
Fix this by adding a aarch64_pcrelative_literal_loads check.
