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.

made IR-based expression evaluation the default.
Also added a new class to hold persistent variables.
The class is empty as yet while I write up a design
document for what it will do. Also the place where
it is currently created (by the Expression command)
is certainly wrong.

- Do all defs correspond to instructions or phis?
- Do all defs dominate all their live ranges?
- Are all live ranges continually reachable from their def?
