test case
For the attached .ll test case,
llc -mtriple armv8-eabi < mod.ll
should generate __aeabi_ldivmod instead of __moddi3. i32 srem/urem is correct
though.
The cause is when data type is i64, LegalizeInterTypes first directly
converts them to calls to RTLIB::SREM_I64(__moddi3) or
RTLIB::UREM_I64(__umoddi3).</pre>
