Create FunctionType::isValidArgumentType to go along with isValidReturnType.
...
Also create isValidElementType for ArrayType, PointerType, StructType and
VectorType.
Make LLParser use them. This closes up some holes like an assertion failure on:
%x = type {label}
but largely doesn't change any semantics. The only thing we accept now which
we didn't before is vectors of opaque type such as "<4 x opaque>". The opaque
can be resolved to an int or float when linking.

Slightly generalize the code that handles shuffles of consecutive loads
...
on x86 to handle more cases. Fix a bug in said code that would cause it
to read past the end of an object. Rewrite the code in
SelectionDAGLegalize::ExpandBUILD_VECTOR to be a bit more general.
Remove PerformBuildVectorCombine, which is no longer necessary with
these changes. In addition to simplifying the code, with this change,
we can now catch a few more cases of consecutive loads.
