With r275532 fixing miscompilation of GVN, "inbounds" on certain GEPs in these
tests cannot be preserved any more. Left a TODO in the tests for future
reference.

We used to be over-conservative about preserving inbounds. Actually, the second
GEP (which applies the constant offset) can inherit the inbounds attribute of
the original GEP, because the resultant pointer is equivalent to that of the
original GEP. For example,
x = GEP inbounds a, i+5
=>
y = GEP a, i // inbounds removed
x = GEP inbounds y, 5 // inbounds preserved
