1. Replace RAPIDJSON_CLZLL with internal clzll …

   RAPIDJSON_CLZLL is defined as macro of __builtin_clzll when
   using gcc to compile. This introduces two issues:
   1. in gcc __builtin_clzll returns int, not uint32_t.
   2. __builtin_clzll return is undefined when input x is 0
   See: https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html
   
   This patch removes RAPIDJSON_CLZLL, merges __builtin_clzll to
   internal clzll with input check and return value explicit cast.
