Remove PHINode::reserveOperandSpace(). Instead, add a parameter to
...
PHINode::Create() giving the (known or expected) number of operands.

Simplify RecursivelyDeleteDeadPHINode. The only functionality change
...
should be that if the phi is used by a side-effect free instruction with
no uses then the phi and the instruction now get zapped (checked by the
unittest).

Make RecursivelyDeleteDeadPHINode delete a phi node that has no users and add a
...
test for that. With this change, test/CodeGen/X86/codegen-dce.ll no longer finds
any instructions to DCE, so delete the test.
Also renamed J and JP to I and IP in RecursivelyDeleteDeadPHINode.

where the element is of a basic builtin type. For example, to get
an i8* use getInt8PtrTy.
