[RFC][PATCH 0/3] implement pseudo->ctype

[Xi Wang <xi.wang@gmail.com>]

This patchset tries to implement Chris's `counter RFC': adding ->ctype
to pseudo, while removing ->type and ->size from instruction.  In this
way, it provides easy access to type information for backend.

The first patch adds ->ctype to struct pseudo and doesn't touch struct
instruction.  It could be applied alone if we really want backward
compatibility.

The second patch does more destructive work.  It removes ->type and
->size from struct instruction and updates client uses.

The third patch updates sparse-llvm in a naive way, which should have
been much simpler with the new ->ctype in pseudo.  I guess in some cases
->ctype is even necessary.  Consider the example below.

void foo(int x, ...);
foo(1, 2, 3LL);

Is it possible to get the types of the 2nd and 3rd arguments in current
code, which are simply PSEUDO_VAL?

Xi Wang (3):
  add ->ctype to struct pseudo
  remove ->type and ->size from struct instruction
  sparse, llvm: sync with new struct instruction
