Log:
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.

    gcc/
 PR target/79041
 * config/aarch64/aarch64.c (aarch64_classify_symbol):
 Avoid SYMBOL_SMALL_ABSOLUTE for literals with pc-relative literals.
    gcc/testsuite/
 * gcc.target/aarch64/pr79041-2.c: New test.
