fix debug counter for Hash counts.

Browse source 
Change debug_counters for Hash object counts:

* obj_hash_under4 (1-3) -> obj_hash_1_4 (1-4)
* obj_hash_ge4 (4-7)    -> obj_hash_5_8 (5-8)
* obj_hash_ge8 (>=8)    -> obj_hash_g8  (> 8)

For example on rdoc benchmark:

[RUBY_DEBUG_COUNTER]    obj_hash_empty                         554,900
[RUBY_DEBUG_COUNTER]    obj_hash_under4                        572,998
[RUBY_DEBUG_COUNTER]    obj_hash_ge4                             1,825
[RUBY_DEBUG_COUNTER]    obj_hash_ge8                             2,344
[RUBY_DEBUG_COUNTER]    obj_hash_empty                         553,097
[RUBY_DEBUG_COUNTER]    obj_hash_1_4                           571,880
[RUBY_DEBUG_COUNTER]    obj_hash_5_8                               982
[RUBY_DEBUG_COUNTER]    obj_hash_g8                              2,189
