vm_core.h (struct rb_iseq_struct): stack_max is uint32_t
* vm_core.h (struct rb_iseq_struct): stack_max is uint32_t
No program will ever need more than a few megabytes of stack,
so there's no sense in using a 64-bit counter for stack
accounting. Packing this with the 32-bit type enum reduces
rb_iseq_struct from 312 to 304 bytes on 64-bit systems.
