Revert r237339 as sanitizer-ppc64-linux1 does not like it.

Complains:

/home/buildbots/sanitizerslave1/sanitizer-ppc64-1/build/llvm/tools/clang/tools/c-index-test/c-index-test.c:829:30: error: format specifies type 'long' but the argument has type 'long long' [-Werror,-Wformat]
                     I, TAK, clang_Cursor_getTemplateArgumentValue(Cursor, I));
                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I'm not sure now how this should be fixed. %lld is non-standard
and not accepted by mingw on Windows while PRId64 is bad for this bot.

Is long long longer than 64 bits here? if not, why is PRId64
incompatible with it? something seems wrong.

Probably all the datatypes should be replaced to unsigned or uint64_t
depending upin requirements instead of the non standard long long.
