debug forms.

- All abstrct vector nodes must have # of elements and element type as their
first two operands.

unsigned foo4(unsigned short *P) { return *P & 255; }
unsigned foo5(short *P) { return *P & 255; }

        blr
_foo5:
        lbz r3,1(r3)

24a22066c4 Fold "and (LOAD P), 255" -> zextload. This allows us to compile: 
unsigned foo3(unsigned *P) { return *P & 255; }
as:
_foo3:
        lbz r3, 3(r3)
        blr

instead of:

_foo3:
        lwz r2, 0(r3)
        rlwinm r3, r2, 0, 24, 31
        blr

and:

unsigned short foo2(float a) { return a; }

as:
_foo2:
        fctiwz f0, f1
        stfd f0, -8(r1)
        lhz r3, -2(r1)
        blr

instead of:

_foo2:
        fctiwz f0, f1
        stfd f0, -8(r1)
        lwz r2, -4(r1)

4f083f08ca Fix a bug that Evan exposed with some changes he's making, and that was 
exposed with a fastcc problem (breaking pcompress2 on x86 with -enable-x86-fastcc).

When reloading a reused reg, make sure to invalidate the reloaded reg, and
check to see if there are any other pending uses of the same register.

a342126820 Refactor some code from being inline to being out in a new class with methods. 
This gets rid of two gotos, which is always nice, and also adds some comments.

No functionality change, this is just a refactor.
