Commit Message

fix: home the sret pointer before the function body

The hidden return pointer arrives in rdi and is not an IR value, so a
control-flow edge drops it without writing its home. The epilogue then
stores the struct through that slot. Straight-line returns kept rdi
live, so the existing sret tests passed. An untaken branch crashes at
-O0 and at -O1 when the callee is not inlined.

Write rdi into the sret slot in the prologue, before the body.

make(0) on a 24-byte struct prints 7 8 9.
