ruby/util.h: DECIMAL_SIZE_OF_BITS
* include/ruby/util.h (DECIMAL_SIZE_OF_BITS): a preprocessor
constant macro to approximate decimal representation size of n-bits
integer.
* iseq.c (register_label): use DECIMAL_SIZE_OF_BITS for better
approximation.
* ext/bigdecimal/bigdecimal.c (BigMath_s_log): ditto.
* common.mk (iseq.o), ext/bigdecimal/depend (bigdecimal.o): add
dependency to ruby/util.h for DECIMAL_SIZE_OF_BITS.
