Add proper EOF handling to Communication & Connection classes:

Add bool member to Communication class indicating whether the
Connection should be closed on receiving an EOF or not.  Update the
Connection read to return an EOF status when appropriate.  Modify the
Communication class to pass the EOF along or not, and to close the
Connection or not, as appropriate.

named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness.  This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

TemplateArgumentLocInfo. Unfortunately, this means that we lose some
internal consistency checking when building a debug Clang. However,
having data structures change size/layout depending on NDEBUG causes
pain for clients of the Clang API.

For most intrinsics, there is no need to allocate a temporary to hold the
result value; just return it directly.

This does not work so well with the -fno-lax-vector-conversions option for
testing the arm_neon.h header but that is a really useful test, so I split
this out to a separate Sema test to check for the warning.

Since we're casting them for the calls to the builtins, we need this to
make sure their types get checked in the same way they would if the intrinsics
were implemented as inline functions.

when an initializer is variable (I handled the constant case in a previous
patch).  This has three pieces:

1. Enhance AggValueSlot to have a 'isZeroed' bit to tell CGExprAgg that
   the memory being stored into has previously been memset to zero.
2. Teach CGExprAgg to not emit stores of zero to isZeroed memory.
3. Teach CodeGenFunction::EmitAggExpr to scan initializers to determine
   whether they are profitable to emit a memset + inividual stores vs
   stores for everything.

The heuristic used is that a global has to be more than 16 bytes and
has to be 3/4 zero to be candidate for this xform.  The two testcases
are illustrative of the scenarios this catches.  We now codegen test9 into:

 call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 400, i32 4, i1 false)
 %.array = getelementptr inbounds [100 x i32]* %Arr, i32 0, i32 0
 %tmp = load i32* %X.addr, align 4
 store i32 %tmp, i32* %.array

and test10 into:

  call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 392, i32 8, i1 false)
  %tmp = getelementptr inbounds %struct.b* %S, i32 0, i32 0
  %tmp1 = getelementptr inbounds %struct.a* %tmp, i32 0, i32 0
  %tmp2 = load i32* %X.addr, align 4
  store i32 %tmp2, i32* %tmp1, align 4
  %tmp5 = getelementptr inbounds %struct.b* %S, i32 0, i32 3
  %tmp10 = getelementptr inbounds %struct.a* %tmp5, i32 0, i32 4
  %tmp11 = load i32* %X.addr, align 4
  store i32 %tmp11, i32* %tmp10, align 4

Previously we produced 99 stores of zero for test9 and also tons for test10.
This xforms should substantially speed up -O0 builds when it kicks in as well
as reducing code size and optimizer heartburn on insane cases.  This resolves
PR279.

This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.
