Global variables don't have a corresponding llvm.dbg.declare, yet it is possible
...
to obtain debug info about them.
Introduce helpers to access debug info for global variables. Also introduce a
helper that works for both local and global variables.

Fix two classes of bugs. First:
...
validate an invariant so that the asmparser rejects a bad construct
instead of the verifier. Before:
llvm-as: assembly parsed, but does not verify as correct!
Invalid struct return type!
i64 (%struct.Type*, %struct.Type*)* @foo
after:
llvm-as: t.ll:5:8: functions with 'sret' argument must return void
define i64 @foo(%struct.Type* noalias nocapture sret %agg.result, %struct.Type* nocapture byval %t) nounwind {
^
Second, check that void is only used where allowed (in function return types) not in
arbitrary places, fixing PR3747 - Crash in llvm-as with void field in struct. We
now reject that example with:
$ llvm-as t.ll
llvm-as: t.ll:1:12: struct element can not have void type
%x = type {void}
