Testcase to go along with commit 118923 ("Have GVN simplify instructions
as it goes"). Before -std-compile-opts only got it down to
%a = tail call i32 @foo(i32 0) readnone
%x = tail call i32 @foo(i32 %a) readnone
%y = tail call i32 @foo(i32 %a) readnone
%z = icmp eq i32 %x, %y
ret i1 %z
while now -basicaa -gvn alone reduce it to
%a = call i32 @foo(i32 0) readnone
%x = call i32 @foo(i32 %a) readnone
ret i1 true
