c7b51b678d First round of ppc long double. call/return and 
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

01b306e575 Refactor the memcpy lowering for the x86 target. 
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

1bb346f9f1 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

dd675a5064 Use the correct result value type instead of using getValueType(0) 
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort
in the included testcase.

803e0d9970 Objective-C was generating EH frame info like this: 
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

fa3a5915b1 Fix for PR1633: Verifier doesn't fully verify GC intrinsics 
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.

8 byte alignment. Implement that.

899c0c9c8d Split eh.select / eh.typeid.for intrinsics into i32/i64 versions. This is needed, because they just "mark" register 
liveins and we let frontend solve type issue, not lowering code :)
