[CSInfo][clang] Enable debug entry values for Mips

[ntesic]

Summary

Debug entry values functionality provides debug information about
call sites and function parameters values at the call entry spot.
Condition for generating this type of information is
compiling with -g option and optimization level higher than zero(-O0).

This patch enables functionality in clang frontend
for mips targets (mips, mipsel, mips64, mips64el).

This would benefit from some kind of test.

@aprantl
Thanks for the feedback. I think we can merge this into child patch, so we can use tests from that patch.
Let me know what you think.

[aprantl]

If that covers the change, sure!
