0c436ab356 Various optimizations. Don't compare two loops' depths 
when they are the same loop. Don't compare two instructions'
loop depths when they are in the same block.

63c020a210 When testing whether one loop contains another, test this directly 
rather than testing whether the loop contains the other's header.

cf32f2bde1 When creating a symmetric SCEV with a constant operand, put 
the constant operand on the left, as that's where ScalarEvolution
will end up canonicalizing to.

ec0120a123 An add recurrence is loop-invariant in any loop inside of its 
associated loop. This avoids potentially expensive traversals
of the add recurrence's operands.

2de47777f4 Optimize ScalarEvolution::getAddExpr's operand factoring code by 
having it finish processing all of the muliply operands before
starting the whole getAddExpr process over again, instead of
immediately after the first simplification.

f7495f286a When analyzing loop exit conditions combined with and and or, don't 
make any assumptions about when the two conditions will agree on when
to permit the loop to exit. This fixes PR7845.

5f1702e4fe Move all the logic for function attributes and call attributes out of the 
AliasAnalysis base class and into BasicAliasAnalyais. This avoids confusion
about where such logic is happening when there are other AliasAnalysis
implementations present.

Move the logic for translating two-callsite getModRefInfo queries into
other AliasAnalysis queries out of BasicAliasAnalysis and into the
AliasAnalysis base class, as it is useful for other AliasAnalysis
implementations.

755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

884dd752c3 Implement AccessesArguments checking in the two-callsite form 
of BasicAA::getModRefInfo. This allows BasicAA to say that two

26ef7c7ab7 Fix memdep's code for reasoning about dependences between two calls. A Ref 
response from getModRefInfo is not useful here. Instead, check for identical
calls only in the NoModRef case.

Reapply r110270, and strengthen it to compensate for the memdep changes.
When both calls are readonly, there is no dependence between them.

109561845b The trouble with testing for "ModRef" and "NoModRef" is that 
one is a suffix of the other, and FileCheck accepts superstrings.
Adjust the output to avoid this problem.

bd33dab633 The two-callsite form of AliasAnalysis::getModRefInfo is documented 
to return Ref if the left callsite only reads memory read or written
by the right callsite; fix BasicAliasAnalysis to implement this.

Add AliasAnalysisEvaluator support for testing the two-callsite
form of getModRefInfo.

5442c71f2e 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.
