9a6ae965d6 Move the APInt form of SCEVUnknown::getIntegerSCEV to SCEVConstant::get, and
use SCEVConstant::get instead of SCEVUnknown::get when constructing a SCEV
for a ConstantInt.

78e02f78ce A first stab at memory dependence analysis. This is an interface on top of
alias analysis, adding caching and lazy computation of queries.  This will
be used in planned improvements to memory access optimizations.

Almost all occurrences of "bytecode" in the sources have been eliminated.

5cec4db6ae Rename ScalarEvolution::deleteInstructionFromRecords to
deleteValueFromRecords and loosen the types to all it to accept
Value* instead of just Instruction*, since this is what
ScalarEvolution uses internally anyway. This allows more flexibility
for future uses.

d19534add9 Add a SCEV class and supporting code for sign-extend expressions.
This created an ambiguity for expandInTy to decide when to use
sign-extension or zero-extension, but it turns out that most of its callers
don't actually need a type conversion, now that LLVM types don't have
explicit signedness. Drop expandInTy in favor of plain expand, and change
the few places that actually need a type conversion to do it themselves.
