#509 Verification error on Intel after spill code

[Ian Rogers]

Bug #1378568 described a bug in OPT_GenericStackManager
that resulted in a patch being backed out. The patch
addressed a problem in OPT_GenericStackManager that on
Intel yieldpoint_osr instructions don't have memory
operands renamed. This results in them refering to HIR
registers that are no longer defined and the ensuing
verification error. The problem comes from PPC yield
point instructions claiming to have memory operands,
which is odd.

I'm raising this bug as #1378568 describes this as a
PPC problem, whereas the current state of the code is
that it is an Intel problem.

It's expected but ugly behavior that yield points will have HIR/LIR registers even if these registers are spilled... Leaving this bug to be reopened when someone thinks this solution is ugly again.
