05:58 PM Ruby Revision 22bc2aa8 (git): Move constant in TestYJIT into test

GC::INTERNAL_CONSTANTS[:RVARGC_MAX_ALLOCATE_SIZE] may not be defined, which
will cause the test file to not be able to load. peterzhu2118 (Peter Zhu)

03:00 PM Ruby Revision 3760fedb (git): Handle shape ID capacity overflow

If we allocate objects larger than 1024 bytes, the capacity in the shape
ID will overflow. This commit fixes it set the capacity to SHAPE_ID_CAPACITY_MAX
in that case and falls back to rb_gc_obj_slot_size instead. peterzhu2118 (Peter Zhu)

Methods with mandatory only support only dumps the ISEQ of the case with

06:20 AM Ruby Revision 916d8c10 (git): Prevent overflow of length bits for embedded structs

Embedded structs only use 7 bits for the length, so it will overflow if
the GC can allocate large slots. We need to add the cap to struct_alloc. peterzhu2118 (Peter Zhu)
