MergeFunctions emits Bitcast from pointer to integer.

But it should be ptr-to-int and int-to-ptr commands. That causes crash for next
case under x86-64 arch:

target datalayout =
"e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64-S128"

define void @f0(i64 %p0) {
entry:
  ret void
}

define void @f1(i64* %p0) {
entry:
  ret void
}
