Stefan Liebler 83653f804d S390: Save and restore r12 in TLS_IE macro. 
The testcases elf/tst-tls1-static and elf/tst-tls2-static
are failing on s390 if gcc is configured with --enable-default-pie.

According to binutils, there are only four valid cases for IE -> LE transition:
lg %rx,(0,%ry)    -> sllg %rx,%ry,0
lg %rx,(%ry,0)    -> sllg %rx,%ry,0
lg %rx,(%ry,%r12) -> sllg %rx,%ry,0
lg %rx,(%r12,%ry) -> sllg %rx,%ry,0

Thus I've adjusted the TLS_IE macro in s390 tls-macros.h files in PIC case
in order to use r12 for the address of global offset table.
The adjusted macro definition is not used if gcc is not configured with
--enable-default-pie.

ChangeLog:

	* sysdeps/s390/s390-32/tls-macros.h (TLS_IE): Use r12 for GOT address.
	* sysdeps/s390/s390-64/tls-macros.h (TLS_IE): Likewise.
