Fix PR2757. Ignore liveinterval register allocation preference if the preference register is not in the right register class. This can happen due to sub-register coalescing.

It's already special-cased and treated as rematerializable within
LiveIntervals; this allows it to be handled by other passes
such as TwoAddressInstrctionPass.

Also, fix a subtle bug in SimplifyDemandedVectorElts'

This is a patch that was originally written by Eli Friedman,
with some fixes and cleanup by me.

(1) code left over from the days of ConstantPointerRef:
if a use of a function is a GlobalValue then that is
not considered a reason to add an edge from the external
node, even though the use may be as an initializer for
an externally visible global!  There might be some point
to this behaviour when the use is by an alias (though the
code predated aliases by some centuries), but I think
PR2782 is a better way of handling that.  (2) If function
F calls function G, and also G is a parameter to the
call, then an F->G edge is not added to the callgraph.
While this doesn't seem to matter much, adding such an
edge makes the callgraph more regular.
In addition, the new code should be faster as well as
simpler.

handle those now, so any that aren't handled should trigger
the abort.

way it handles the type of the condition is breaking plain
scalar select in the case that the value is a
forward-reference.

Fix a constant lowering bug. Now we can do load and store instructions with funky getelementptr embedded in the address operand.

the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

and, if so, to return a vector of boolean as a result;

Extend the select LLVM IR instruction to allow you to specify a result
type which is a vector of boolean, in which case the result will be an
element-wise selection instead of choosing one vector or the other; and
