I compiled below C code for aarch64 in lto using gold
(--target=aarch64-linux-gnu -flto -fuse-ld=gold). After r278338, two
globals, GVi32_a and GVi32_b, are [4 x i8] type in the input IR to
GlobalMerge. Therefore, GlobalMerge do not even start to handle them
because as of now it ignores fancy-aligned globals. Before r278338,
GVi32_a and GVi32_b seems to be i32 in the input IR to GlobalMerge. Is
this change in the input IR expected ?
