Like rLLD354040.
Previously, for unrecognized relocation types, in -no-pie/-pie mode, we got something like:
foo.o: unrecognized relocation ...
In -shared mode:
error: can't create dynamic relocation ... against symbol: yyy in readonly segment
Delete the default case from AArch64::getRelExpr and add the error there.
