b2143b6247 Remove the experimental AliasAnalysis::getDependency interface, which
isn't a good level of abstraction for memdep. Instead, generalize
AliasAnalysis::alias and related interfaces with a new Location
class for describing a memory location. For now, this is the same
Pointer and Size as before, plus an additional field for a TBAA tag.

Also, introduce a fixed MD_tbaa metadata tag kind.

79fca6fea8 Thread const correctness through a bunch of AliasAnalysis interfaces and
eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

d8cc7be026 Add INSTANTIATE_AG_PASS, which combines RegisterPass<> with RegisterAnalysisGroup<> for pass registration.

b41fc9f05c LibCallAliasAnalysis doesn't use TargetData.

15ccbf59a9 Let libcall semantics decide whether it knows about functions
with definitions or not.

d208a803a6 Use static and anonymous namespaces consistently with other passes.

f03893acf0 put LibCallAliasAnalysis into anonymous namespace to avoid
clashes on ::X

029840c935 Add a new LibCallAliasAnalysis pass, which is parameterized
by an instance of LibCallInfo to provide mod/ref info of
standard library functions.  This is powerful enough to
say that 'sqrt' is readonly except that it modifies errno,
or that "printf doesn't store to memory unless the %n
constraint is present" etc.
