0daeed270b Use LoopInfo's getLoopLatch() instead of doing what it does manualy.

53f2ae268a Don't use an induction variable type as a memory access type.
Use VoidTy instead, to be properly conservative.

1a6d31aee6 Add a constructor for BuildVectorSDNode and revert the temporary workaround
from 66280.  I was unable to verify this with gcc-3.4.6, but with gcc-3.3 it
avoids the "base class with only non-default constructor in class without
a constructor" warning.  Apparently that warning was promoted to an error
in gcc-3.4.

f231c07228 Make the code generator rip of dead constant expr uses before deciding
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.

a9a9e07d1c 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}
           ^
