[Darwin, PPC] Use Darwin9 bundle header for Rosetta builds.
On Darwin10 it's possible to make a 32b PPC build using the
'Rosetta' emulator. However, these builds need to make use of
Darwin9 crts (for exes, dylibs and bundles). This adds the
change to cater for bundles.

[PATCH] Fix PR91790 by considering different first_stmt_info for realign
As PR91790 exposed, when we have one slp node whose first_stmt_info_for_drptr
is different from first_stmt_info, it's possible that the first_stmt DR isn't
initialized yet before stmt SLP_TREE_SCALAR_STMTS[0] of slp node. So we
shouldn't use first_stmt_info for vect_setup_realignment, instead we can use
the one based on first_stmt_info_for_drptr DR with additional adjustment by
bumping the distance from first_stmt DR.
