[reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a false

In this particular case, R6 was being spilled by the register scavenger when it
was in fact dead.  The isUsed function reported R6 as used because the R6_R7
alias was reserved (due to the fact that we've reserved R7 as the FP).  The
solution is to only check if the original register (i.e., R6) isReserved and
not the aliases.  The aliases are only checked to make sure they're available.

The test case is derived from one of the nightly tester benchmarks and is rather
intractable and difficult to reproduce, so I haven't included it.

Fix a crash observed by Shuxin Yang.  The issue here is that LinearizeExprTree,
the utility for extracting a chain of operations from the IR, thought that it
might as well combine any constants it came across (rather than just returning
them along with everything else).  On the other hand, the factorization code
would like to see the individual constants (this is quite reasonable: it is
much easier to pull a factor of 3 out of 2*3 than it is to pull it out of 6;
you may think 6/3 isn't so hard, but due to overflow it's not as easy to undo
multiplications of constants as it may at first appear).  This patch therefore
makes LinearizeExprTree stupider: it now leaves optimizing to the optimization
part of reassociate, and sticks to just analysing the IR.

The code pattern "imm0_255_neg" is used for checking if an immediate value is a small negative number.
This patch changes the definition of negative from -0..-255 to -1..-255. I am changing this because of
a bug that we had in some of the patterns that assumed that "subs" of zero does not set the carry flag.
