Test file showing the bug

Compiling the attached file with `llvm-gcc -O3 -c test.c -emit-llvm -S -o
test.ll`  results in two malloc instructions with different arguments:

1) %tmp11617 = malloc [11 x %struct.foo*]               ; <[11 x
%struct.foo*]*> [#uses=2]
2) %tmp315 = malloc %struct.foo         ; <%struct.foo*> [#uses=2]

It seems that (2) is the correct behaviour and that (1), while allocating the
correct size, should use 'malloc %struct.foo' instead.
