InstSelectSimple.cpp: Refactor out conversion of byte, short -> int
  from visitReturnInst() to new method, promote32().
 Use it in both visitReturnInst() and visitCallInst().

llvm-svn: 4839

InstSelectSimple.cpp: First draft of visitCallInst method, handling
 int/float args.
X86InstrInfo.def: Add entries for CALL with 32-bit pc relative arg, and
 PUSH with 32-bit reg arg.

(1) Applied patch from Casey to implement iterator::operator= correctly:
    it should use a pointer, not a reference.
(2) Added operators == and !=, and method all().
(3) Important bug fix: excess bits need to be ignored in operations
    like ==, count(), and all().  We do this by ensuring excess bits
    in the last bitset are always 0.

before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

Also some major fixes within IPModRef.cpp.

    We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.
