f8a3a62cdb Now that the X86 Maximal Stack Alignment Check pass has been removed (i.e., 
r168627), we no longer need to call the freezeReservedRegs() function a second
time.  Previously, this pass was conservatively adding the FP to the set of
reserved registers, requiring the second update to the reserved registers.

2463f67c49 [reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a false 
positive.

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.

until I manually rerun benchmarks. But reducing unit tests is a very
high priority.
