Improve method table performance by rehashing at 75% load factor.
...
The method table (mt_tbl) in src/class.c previously only rehashed when it became completely full. With linear probing, this could lead to significant performance degradation for lookups and insertions as the table approached full capacity.
This change introduces a load factor (MT_LOAD_FACTOR_NUM/MT_LOAD_FACTOR_DEN, set to 3/4 or 0.75). The mt_put function now checks if adding a new element would cause the table's size to meet or exceed this load factor relative to its allocated capacity. If so, it triggers a rehash before inserting the new element.
This helps maintain more empty slots in the hash table, improving the average-case performance of linear probing and reducing the likelihood of worst-case scenarios. The existing initial allocation size and doubling strategy for rehashing are retained.

mruby-compiler (gen_move): avoid optimization of ADDI/SUBI
...
ADDI/SUBI may fall back to method call that may clear block argument
place holder, which may be a live register. So we cannot directly call
ADDI/SUBI over local variables.

mruby-compiler: add y.tab.c in the repository again; close #6515
...
Since we have introduced lrama, everyone can generate same `y.tab.c`
on any platform, without installing Bison. That was the reason we have
removed `y.tab.c` from the repository. But this change cause #6515 and
bothered out-of-tree builds. So we (reluctantly) added `y.tab.c` again.

class.c (mt_rehash): Fix mrb_calloc argument order
...
Since mrb_calloc() (along with mrb_calloc) takes two arguments: nmemb
which is number of array elements, and size which is size of the array.
Of course, revsersing does not change the behavior, but we'd like to
respect the original design intention of calloc(3).
