hppa: Fix reload error with atomic code [BZ #18787]
As noted in the bug, the asm operands need to be copied to register
variables to avoid operand reloads in the principal asm of the macro.
See the arm implementation for reference. Otherwise we get:
../sysdeps/unix/sysv/linux/hppa/bits/atomic.h:68:6: error:
can't find a register in class 'R1_REGS' while reloading 'asm'
Build tested on trunk with gcc-4.8. Similar patch has been tested
with 2.19 on Debian hppa-unknown-linux-gnu.
