op.h: Add additional padding to struct opslab to ensure proper alignment
On m68k, the natural alignment is 16 bits which causes the opslab_opslot
member of struct opslab to be aligned at a 16-bit offset. Other 32-bit
and 64-bit architectures have a natural alignment of at least 32 bits, so
the offset is always guaranteed to be at least 32-bit-aligned.
Fix this by adding additional padding bytes before the opslab_opslot
member, both for cases when PERL_DEBUG_READONLY_OPS defined and not
defined to ensure the offset of oplab_slots is always 32-bit-aligned.
On architectures which have a natural alignment of at least 32 bits,
the padding does not affect the alignment, offsets or struct size.
