Austin Clements 0293a1f308 runtime: avoid large object stack copy in traceStackTable.dump
Following up on the previous CL, this CL removes a unnecessary stack
copy of a large object in a range loop. This drops another 64 KiB from
(*traceStackTable).dump's stack frame so it is now roughly 80 bytes
depending on architecture, which will easily fit on the system stack.

For #53979.
