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.

Nice addition to the examples and also a starting point for Sanjiv to work on.

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.

Also, there were a bunch of flags with no text in --help because the square
brackets were in the wrong place. I've fixed those too.

building a vector which is all zeros/undef except for the bottom 
element, where the bottom element is an i8 or i16.

Make ParmVarDecl::getDefaultArg() more robust, it now asserts that the argument is not unparsed. Add a new hasDefaultArg() and use it in places where getDefaultArg() was called when the argument was unparsed.
