Adhemerval Zanella c261718b3f sparc: Avoid clobbering register parameters in syscall 
The sparc INTERNAL_SYSCALL macro might clobber the register
parameter if the argument itself might clobber any register (a function
call for instance).

This patch fixes it by using temporary variables for the expressions
between the register assignments (as indicated by GCC documentation,
6.47.5.2 Specifying Registers for Local Variables).

It is similar to the fix done for MIPS (bug 25523).

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
