[gabi++] Fix bug: incorrect parameter type.

To be compatible with lower-level library API, the second parameter
type of _Unwind_SetIP should not be uint64_t, or it will
occur type casting error, which causes stack unwinding fail on Mips.

After this commit, I believe we can claim that
stlport w/ gabi++ has good support on exception handling
on all ARM, x86 and Mips platforms.
