a2f3e13cf4 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.

863bdc332d Emit integer x<1 as x<=0, as comparisons with zero (now includeing 
64-bit) can use test instead of cmp with an immediate.

51d1929b9e Use "test reg,reg" in place of "cmp reg,0" for 64-bit operands. This was 
previously only done for 32-bit and smaller operands.

1de0c86717 Add support for having different alignment for objects on call frames. 
The x86-64 ABI states that objects passed on the stack have
8 byte alignment. Implement that.

122bf4be7e 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 :)

imagine how the original bug could be reintroduced.

ff33241e16 call libc memcpy/memset if array size is bigger then threshold. 
Coping 100MB array (after a warmup) shows that glibc 2.6.1 implementation on
x86-64 (core 2) is 30% faster (from 0.270917s to 0.188079s)
