* turn GC allocations to allocas if possible
Phobos1 of DMD too has alloca, so can this optimization be folded in DMD too?
I doubt it, these look like LLVM specific optimisations.
* simplify or remove certain calls to D runtime functions
What calls?
Looking at the source code (gen/passes/*.cpp):
* _d_arraysetlengthT
* _d_arraysetlengthiT
* _d_array_cast_len
* _d_array_slice_copy
* _d_allocmemoryT
* _d_newarrayT
* _d_newarrayiT
* _d_newarrayvT
* _d_newarraymT
* _d_newarraymiT
* _d_newarraymvT
* _d_allocclass
Are the runtime calls currently optimized. There may be more that I've
missed, that looks like all of them though.
