s390: Split up s390-linux-tdep.c into two files

Currently all target dependent code for s390 is in one file,
s390-linux-tdep.c.  This includes code general for the architecture as
well as code specific for uses in GNU/Linux (user space).  Up until now
this was OK as GNU/Linux was the only supported OS.  In preparation to
support the new Linux kernel 'OS' split up the existing s390 code into a
general s390-tdep and a GNU/Linux-specific s390-linux-tdep.

Note: The record-replay feature will be moved in a separate patch.  This
is simply due to the fact that the combined patch would be too large for
the mailing list.  This requires setting the process_record hook during
OSABI init to keep the code bisectable.  The patch moving record-replay
cleans up this hack.
