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.

Adapt the x86 build_vector dagcombine to the current state of the legalizer.
...
build vectors with i64 elements will only appear on 32b x86 before legalize.
Since vector widening occurs during legalize, and produces i64 build_vector
elements, the dag combiner is never run on these before legalize splits them
into 32b elements.
Teach the build_vector dag combine in x86 back end to recognize consecutive
loads producing the low part of the vector.
Convert the two uses of TLI's consecutive load recognizer to pass LoadSDNodes
since that was required implicitly.
Add a testcase for the transform.
