Use address-taken to disambiguate global variable and indirect memops.
...
Major steps include:
1). introduces a not-addr-taken bit-field in GlobalVariable
2). GlobalOpt pass sets "not-address-taken" if it proves a global varirable
dosen't have its address taken.
3). AA use this info for disambiguation.

Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID
...
This is done to avoid odd test failures, like the one fixed in r171243.
My previous regex was not good enough to find these.

GlobalOpt forgot to handle bitcast when analyzing globals. Found by inspection.

Some optimizations done by globalopt are safe only for internal linkage, not
...
linkonce linkage. For example, it is not valid to add unnamed_addr.
This also fixes a crash in g++.dg/opt/static5.C.

Add unnamed_addr when we can show that address of a global is not used.
