Yeah, I guess !TARGET_PARTIAL_REG_STALL || optimize_function_for_size_p

So the immediate reason is that between analysis and transform whether we
consider the shift vectorizable changes. That's because we code generated
a live lane which ended up changing operands in stmts

using these kind of flags on standard patterns is at least fragile?

So I wonder if we can use "local costing" to decide a gather is always OK
compared to the alternative with peeling for gaps. On x86 gather tends
to be slow compared to open-coding it.

The issue is really unexpected if-conversion which ends up putting the
vector copy of an innner loop outside of the enclosing loop of a scalar
loop. Such mishap usually happens because of simplifications.
