f7e498138f Don't remove aggregate-typed module level constants before encoding functions
since functions may contain aggregate constants too.

add a few suggestions from looking at some assembly code.

92fcdcac54 Use expandCodeFor instead of expand when the result will be
immediately casted. At present, this is just a minor code
simplification. In the future, the expansion code may be able
to make better choices if it knows what the desired result
type will be.

a5f54a06b0 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.

7a5e55509b 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.
