mips: implement CLEAR_CALLER_SAVED_REGS for memcheck tests

Browse Source 
Implement CLEAR_CALLER_SAVED_REGS macro that is used for some memcheck
tests. This is done in order to clear temporary registers that still
might be holding pointers to lost memory regions.
Similar change has been made for PPC.

This fixes the following tests:

memcheck/tests/leak-cases-full           (stderr)
memcheck/tests/leak-cases-summary        (stderr)
memcheck/tests/leak-cycle                (stderr)
memcheck/tests/lks                       (stderr)

on some MIPS platforms.

Patch by Aleksandar Rikalo.
