VMCore: add assert for miscompile
...
See PR11652. Trying to add this assert to
setSubclassData() itself actually prevented
the miscompile entirely, so it has to be here.
This makes the source of the bug more obvious
than the other asserts triggering later on did.

Cleanup stack/frame register define/kill states. This fixes two bugs:
...
1. The ST*UX instructions that store and update the stack pointer did not set define/kill on R1. This became a problem when I activated post-RA scheduling (and had incorrectly adjusted the Frames-large test).
2. eliminateFrameIndex did not kill its scavenged temporary register, and this could cause the scavenger to exhaust all available registers (and its emergency spill slot) when there were a lot of CR values to spill. The 2010-02-12-saveCR test has been adjusted to check for this.

Change CaptureTracking to pass a Use* instead of a Value* when a value is
...
captured. This allows the tracker to look at the specific use, which may be
especially interesting for function calls.
Use this to fix 'nocapture' deduction in FunctionAttrs. The existing one does
not iterate until a fixpoint and does not guarantee that it produces the same
result regardless of iteration order. The new implementation builds up a graph
of how arguments are passed from function to function, and uses a bottom-up walk
on the argument-SCCs to assign nocapture. This gets us nocapture more often, and
does so rather efficiently and independent of iteration order.
