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.

b6f5b00c3b Add new TargetLowering code to provide the final register type that an
illegal value type will be transformed to, for code that needs the
register type after all transformations instead of just after the first
transformation.

copy-to-regs for various purposes into separate functions so that they
are done consistently.

7f32156bb9 Generalize MVT::ValueType and associated functions to be able to represent
extended vector types. Remove the special SDNode opcodes used for pre-legalize
vector operations, and the special MVT::Vector type used with them. Adjust
lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.

This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.
