whether a global is dead or not.  This should fix PR3749 - linker adds 
spurious use to appending globals.  I can't reasonably add a testcase
for this, because the bc writer/reader strip dead constant users.

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}
           ^

llvm-svn: 66394

by checking that the top-level type of a gep is sized. This
causes us to reject the example with:

llvm-as: t2.ll:2:16: invalid getelementptr indices
getelementptr i32()* null, i32 1
              ^

This prevents caret diagnostics from the scratch buffer from 
including other tokens in the scratch buffer that occurred beforei
them.

llvm-svn: 66375

end of line instead of just the end of buffer.  Scratch buffers contain
embedded \0's between tokens which are logic line separators.  If a 
normal text buffer contains \0's, it doesn't make a lot of sense to include
them in the caret diag output anyway.

llvm-svn: 66374

\0's to created tokens instead of making all clients do it.  No functionality
change.

from being a NamedDecl to being and ObjCImplDecl.  This fixes
some valgrind issues where ObjCCategoryImpl's were being cast
to NamedDecl and then stuck on name lookup datastructures.
