9d10086797 Don't record the increment instruction; just recompute it from the Phi 
if needed. This simplifies the code a little, and is needed for an
upcoming refactoring.

96c96b46e9 Fix PR3724 by searching for the largest free block when 
allocating memory in the JIT.  This is insanely inefficient, but
hey, most people implement their own memory managers anyway.

Patch by Eric Yew!

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

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}
           ^
