YJIT: Initialize code buffer with PUSH DS
PUSH DS triggers the #UD processor exception in 64-bit mode, which the
OS translates to a SIGILL. Unlike INT3, this triggers the usual crash
reporter, which makes failures easier to notice. When there is a
debugger attached, the PUSH DS pauses execution just like INT3.
