337b10f6ed store register usage of ret instructions (abi fuzz) 
So far I was ignoring register uses of return instructions
and it was working because at most one register could be
returned.  Now that more complex returns are supported it
is necessary to keep track of the registers used by
returns.

The abi fuzzer triggered an assertion failure in the
register allocator with the following IL:

        R1 =l load [%t16]
        R3 =l load [8 + %t16]
        ret

The regalloc would use R1 for %t16, and then a (nice)
assertion realized the inconsistent state because R1
could only be def'd by an assignment to %t16.

50c5af4290 Allow trailing and ',' and references in data. 
This change adds support for two things:

		data $foo {l 123,}

	Which allows easier machine generation of data
	statements. It also adds the ability to parse
	and emit references in data declarations.

'_' is ok to start a symbol, and '$' is an acceptable character
	within a symbol.

0679df0b56 break Tmp.phi chains at phi nodes 
This makes sure the Tmp.phi "chain" is at most
two elements long.  Something smarted could be
possible, but union-find with path compression
is still not exactly what I want.

7abf421ea2 make phi-class handling more local 
The phi classes are no longer in a union-find
structure, instead each temporary argument of
a phi node gets a pointer to it.  The hinting
of the phi node is then shared with its the
one of its arguments.  When liveness proceeds
and finds out that two elements with same
hinting (a phi node and one of its arguments
or two arguments of the same phi node)
interfere, one of them has its phi pointer
reset, that way, the hinting won't be shared.
