exec: Reorganize the GETRA/GETPC macros
Always define GETRA; use __builtin_extract_return_addr, rather than
having a special case for s390. Split GETPC_ADJ out of GETPC; use 2
universally, rather than having a special case for arm.
Rename GETPC_LDST to GETRA_LDST to indicate that it does not
contain the GETPC_ADJ value. Likewise with GETPC_EXT to GETRA_EXT.
Perform the GETPC_ADJ adjustment inside helper_ret_ld/st. This will
allow backends to pass along the "true" return address rather than
the massaged GETPC value. In the meantime, double application of
GETPC_ADJ does not hurt, since the call insn in all ISAs is at least
4 bytes long.
