fix a bogus assertion exposed by a recent change: packing the
struct may cause it to shrink more than one byte. Before
my recent changes we compiled the new test into:
%0 = type { [6 x i8] }
@x = global %0 { [6 x i8] undef }, align 2 ; <%0*> [#uses=0]
which is obviously bogus. Now we compile it into:
%0 = type <{ i32, i8, i8 }>
@x = global %0 zeroinitializer, align 2 ; <%0*> [#uses=0]
Where the last byte only is tail padding.
