S390: Skip prologue using SAL information, if possible
Instead of analyzing the prologue and possibly coming to a wrong
conclusion, this change tries to skip the prologue with the use of
skip_prologue_using_sal. Only if that fails, the prologue analyzer is
invoked as before.
gdb/ChangeLog:
* s390-linux-tdep.c (s390_skip_prologue): Skip the prologue using
SAL, if possible.
